Ian Clayton Gallagher was born in 1996 in Metz, and is often the most strong-hearted, persistent, and goofy -yet currently reckless- third oldest child in the Gallagher family. He is presumably the product of a PCP-fueled affair between his mother Monica Gallagher and Frank Gallagher's brother, Clayton Gallagher, in the summer of 1995. Ian has been diagnosed with Bipolar Disorder; he currently refuses to visit the doctor and does not believe he needs to take medication. For these reasons his behavior has been erratic and out of control, worrying his family. He is a high school drop out, having left his education behind when he illegally enlisted in the army at the end of Season 3. While in the army, Ian attempted to steal a helicopter, and was a wanted criminal on at least two charges: attempted theft of government property and impersonating his older brother, Phillip Gallagher. He has been in an on-again-off-again relationship with the aggressive neighborhood thug, Mickey Milkovich, and was best friends with Mickey's sister, Mandy Milkovich; he has complete hatred for Mandy's abusive boyfriend, Kenyatta, with whom she moved away to Indiana in Season 5. He helped around the house and assisted Mickey and Svetlana with the care of their son Yevgeny.

After spiraling out of control, Ian becomes a religious fanatic in Season 8 and is arrested. During Season 9, Ian is sent to prison to serve a two-year sentence, where he is reunited with Mickey Milkovich and his character was temporarily retired from the series, making an appearance in the season finale before Fiona leaves. Ian returns in Season 10 with Mickey and both are eventually paroled. Ian struggles with life after prison, building a future with Mickey and his own insecurities, but eventually he and Mickey get engaged and are eventually married.

Personality

Ian is not as intelligent as Lip, but he is more physically fit. He is described by Frank to having an excellent work ethic in nearly everything he does. He is often uncertain of what he wants to do in his life, but once he makes a goal for himself he goes after it 100 percent.

Ian is also self-conscious of his bipolar condition, which he inherited from his mother and often feels inadequate as it prevents him from certain things. He sometimes refuses to admit that he has a problem when his condition causes him to go off his usual path.

Ian gets along with all his siblings who were aware of his sexuality long before he revealed it and accepted regardless. He is closest to Lip and Fiona but does get along with his younger siblings and often help shield them from Frank's influence. Ian was devastated by the betrayal of Samantha Slott who told the army of his AWOL choices. However, he did try to redirect Samantha's son Chuckie Slott from his misguided views from juvie.

Ian like his siblings resents his father Frank for his neglect and his treatment of him since his mother Monica left them. For some time, Ian felt his father despised him the most. However, he was greatly surprised to learn Frank wasn't his biological father but rather his uncle. After meeting his presumed father (Frank's brother), Ian chose not to broach the subject and accepted Frank was his father, just as Lip and the others are his siblings. Interestingly enough, Frank also claims Ian is still his son while not scorning his sexuality and accepting him no matter what. Despite stating he hates him, Ian was worried when Mickey plotted to kill Frank for discovering he was gay. Ian also warned Frank of the danger he was in but listened to his father's words about his life. Ian was even present for Frank's time in the hospital when it looked he was going to die from liver failure and even seemed sad. However, he went back to his usual reaction to Frank after he got a new liver and survived. After Frank ruined Fiona's wedding, Ian took part in throwing Frank off the bridge, he wasn't surprised to see him alive when he returned and didn't try to help him in his moment of pain. Ian also expressed pleasure in Frank's disownment until Frank took revenge by taking Liam and blocking the family out of the house. This tension skyrocketed to the point where he and Lip were tortured by Frank with a raccoon and Frank created a new family while sending him away. Ian's anger mellowed when he introduced Trevor to Frank and still called Frank his father. However, his dislike remained as he tried to attack his father after he tried to return home but soon relented and slowly forgave his father when he helped Liam and fix the house. Ian made full amends with Frank after seeing his grief at Monica's death and hearing him express pride in them, despite their past. In the month after, Ian was also surprised to see Frank put in the effort to change and saved him along with the rest of the family from an armed meth-head while realizing Frank was holding back on him for years in his attacks on him. Though not entirely convinced but grateful for the rescue, Ian seemed to encourage Frank's actions and was pleased that he put in the effort to bond with Liam. Regardless, Ian does show that he cares for Frank and was pleased to see him happy when he turned his and Mickey’s wedding.

Ian is gay and has had several troubled relationships over the course of the series. He had several flings with Kash and Lloyd but neither of them worked out because of their complicated lives getting too much for him, resulting in Ian dumping them. His first love was the neighborhood thug Mickey, who was the person that he wanted to be with all the time but he was devastated Mickey's pride and reaction to his bipolar disorder blocked that. His first true relationship was with firefighter Caleb who was different from all his partners in that they were doing normal things, as they went on dates and confided in personal secrets: Ian being bipolar and Caleb being HIV positive. Caleb was also more encouraging, as he pushed Ian to fight to be a paramedic, something that was a success. Their relationship lasted a month, as Ian discovers Caleb was bisexual and cheating on him with women. Ian's next partner was Trevor, who is transgender and showed a mutual attraction to him. Though Ian just broke up with Caleb, he felt different with Trevor and after moving past differences, they slowly built a relationship once they found common interests. Ian ruined his chances by cheating on Trevor when hooking up with Mickey and nearly running off with him. However, Ian returned to Trevor and they started to reconcile until Ian became a religious fanatic. In prison, Ian reunited with Mickey and they resumed their status. Ian and Mickey had a real relationship in six months that passed but things became tumultuous due to the fact that they would constantly fight about small things. Regardless, they still cared for one another as Mickey prevent Ian from ruining his parole meeting and helped Ian in getting a phone for him to see his new nephew Freddie Gallagher. Ian hesitates at the idea of marrying Mickey, eventually revealing that a lot of it stems from insecurities over how Mickey could love Ian with all of his issues when Mickey could potentially find someone better. After overhearing Byron bad-mouthing Mickey and his qualities, Ian is inspired to not only leap to Mickey's defense, but to propose to Mickey himself. Despite the turbulence at their wedding plans and the reactions of Mickey’s father, Ian was ultimately able to marry Mickey with the help of his family, friends and even his old Gay Jesus followers. With Mickey as his new husband, Ian couldn’t help but be happy about finally finding the person he truly wanted. The only sadness Ian showed was that Monica couldn't be there to witness the wedding.

This also leads to Caleb saying Ian should get tested. Ian does, and goes to the doctor with Caleb, and his results are negative. The nurse also asked Ian how many sexual partners he had had, which led to Caleb leaving the room because Ian did not want to reveal that to Caleb. Later Ian tells Caleb that he truly did not know how many because he used to dance at a strip club "and worked the back of the house as much as the front". Caleb seems to be okay with Ian's past.

He and Lip teased Carl for his circumcision but stop after he tells him that it already hurt without them making him feel less like a Gallagher. That night, Ian and his siblings try to get rid of Frank but he maintains his stance and drops a raccoon to torture them.

Due to this, he takes a break from work. He is not too pleased when Fiona lays down ground rules to earn a keep in their house. When Veronica appears to tell them something about Frank, Ian sees Frank has opened a homeless shelter in a empty house not far from the house. Ian protests his father's choice but Frank tells him along with his other children (except Liam) to leave him alone since they have shown him how they feel (throwing him off a bridge and insulting his since his return) and they leave.

When he returns, he meets Trevor and takes an interest in him, as he seems like the opposite of Caleb in character. He confesses to be a transgender man. Ian unintentionally offends Trevor with his ignorance. Ian apologizes. Later on, Ian introduces Trevor to his father. Trevor initially likes Frank because he believes Frank is trying to help the community by opening a homeless shelter.

As the seventh season progresses, Trevor introduces Ian to some LGBT+ friends. Ian starts to learn that the world is not only black and white and gray and he is also falling for Trevor, sensing that his feelings are not mutual this time. But luckily, Trevor kisses him during a party. After this kiss, both of the guys discuss and seemingly both of them have worries. Trevor thinks Ian is afraid to date a trans man. Ian thinks that they only kissed because they were drunk, and that there was nothing special about it for Trevor. This discussion ends with the two kissing again in a "friendly" manner. Ian now wants to sleep with Trevor but he is confused about how to approach him and he wants Kev's help. As a straight man, Kevin gets more confused than Ian so he cannot be of much help. Ian tries to act normal when he is with Trevor but he cannot help ending up weirdly. This overall weird condition lasts till Ian loses an injured woman and goes to Trevor's house for comfort. Since Trevor is the only person Ian has wanted to tell about the incident, the two characters are about to have sex. However, they both want to top, therefore they cannot have sex at the moment, and they laugh about it. After some time they manage to have sex.

Ian and Trevor become an official couple and Trevor comes to realize the "true" Frank. Ian continues to keep Frank out, even attacking him to force him to leave. Eventually, he mellows out after Frank fixes up the house and helps Liam enter private school; he also permits him to walk his brother to school though threatens him with a bat after pepper spraying him.

Ian does not listen to her, saying "You just appear in no time and ruin our lives," and leaves Monica with Trevor. Then we see Trevor with Ian, now he volunteers to show his ID to Ian. Later, outside the Gallagher house, a detective informs Ian, Trevor, Fiona, and Lip that Mikhailo Aleksandr Milkovich escaped from prison. Ian promises Trevor that he will not get involved with Mickey again. The next morning, a stranger bumps into Ian on his way to work and continues walking. Ian then hears a burner phone ring from the ground, apparently dropped by the stranger. Ian answers the phone and is greeted by Mickey asking if Ian missed him. He then tells Ian to meet him in an hour and to drop the phone in the sewer. Ian initially goes to work like normal, but tells Sue that he is sick and leaves. Ian then goes to the meeting place, where he is blindfolded and forced into a van. Ian is taken to some high school bleachers where Mickey is waiting for him.

Mickey then asks Ian if the police talked to him, and Ian tells Mickey that he did not snitch. Mickey then tells Ian that he plans to get a fake ID, some cash, and flee to Mexico with his cellmate and asks Ian to join them. He tells Ian to think about it, and leaves another burner phone for Ian. Ian asks Fiona for advice by asking what her life would be like if she went away with Jimmy Steve. Fiona tells him that she is proud of him because he improved his life and that Mickey would ruin his progress.

Ian ultimately decides to meet up with Mickey that night. Mickey tells Ian, "I knew you'd come," and kisses him passionately. Ian initially returns the kiss, but soon pushes Mickey away. Ian tells Mickey that he's "got [his] shit together now" and even has a boyfriend. Mickey seems unfazed and asks, "Then why are you here?" Ian initiates the kiss this time, and the two have sex at the docks. The next morning, Ian wakes up in the van cuddling with Mickey. While Mickey is still sleeping, Ian leaves a message on Trevor's phone saying he misses Trevor. Ian then wakes Mickey up to let him know that Ian has to leave for work. Mickey asks if he will see Ian again, and Ian takes the unlit cigarette out of Mickey's mouth to kiss him before replacing the cigarette and leaving.

Ian meets up with Mickey again before Mickey plans to leave. Ian still has not told Mickey if he plans to go to Mexico with him, so Mickey asks, "Is this goodbye?" Ian answers by tossing his bag in the front seat and getting in the car.

On the road, Mickey pulls the car over and tells his cellmate to get out of the car so Ian and Mickey can have sex. Later, when they stop at a gas station, Mickey and his cellmate go inside the store while Ian stays in the car. Ian hears gunshots and sees Mickey and his cellmate run out.

Then, Fiona for the last time visits Ian in his room to fix the things between them, Ian now seems like he's calmer. He tells Fiona that he shouldn't have spent time on trivial things while he had bigger problems, and Fiona asks what they are. Ian doesn't reply.

The very homosexual boy who was forced to be heterosexual in the first place tells Ian he'll go there. This whole scene is being recorded by a girl among the audience and it ends with the gay boy's dad, calling him back. Ian intervenes and asks the dad if he wants his "ass, kicked by a h-o-m-o-s-e-x-u-a-l". The dad stops, calling his son and some other homosexual people follow Ian and Trevor, out of the Church.

The girl who recorded the scene apparently posted it to YouTube and the homeless kids know about it. They thank Ian, and the boy who tried to commit suicide hugs him. In the next episode, Ian is seen what he told the Priest he'll do: having sex with Trevor.

As he is about to kidnap Blake, Ian makes a speech: "My God's a gay, my God's a trans, my God's a junkie."
