Devon Hamilton (also Winters) is a fictional character from The Young and the Restless, an American soap opera, portrayed by Bryton James. The character made his first appearance on June 1, 2004. He was introduced as a homeless teenager who is taken in by the Winters family, the core African-American family within the series. Drucilla Winters (Victoria Rowell) sympathizes with Devon because she too was a product of the foster care system. Drucilla and her husband Neil (Kristoff St. John) raise Devon along with their daughter Lily (Christel Khalil) and legally adopt him in 2006.

Unlike most young male characters whose stories typically centered around romance and teen angst, the character of Devon became a vehicle for social and human interest stories, focusing on the challenges of having a drug addict for a parent, being a product of the foster care system, and deafness. While Devon has a consistent love interest, the romance was rarely displayed and severely undeveloped. In 2009, the character was involved in a controversial storyline in which he had an affair with Tyra Hamilton (Eva Marcille), a woman he'd come to know as his aunt, though it was later revealed they are not related. The foster care, meningitis and deaf story arcs received critical acclaim for their social impact and earned James five Daytime Emmy Award nominations for Outstanding Younger Actor in a Drama Series and James won the award in 2007. James also earned seven NAACP Image Award nominations for Outstanding Actor in a Daytime Drama Series and he won the award in 2009.

In 2011, the character would be written into more traditional soap opera plots starting with the revelation that he is the long lost grandson of the wealthy Katherine Chancellor (Jeanne Cooper). However, the plot twist would only bring him closer to his adoptive father, Neil. In 2013, Devon inherits the bulk of Katherine's billion dollar estate which turns his life upside. In 2014, Devon enters into an affair with Neil's young wife Hilary Curtis (Mishael Morgan). Devon's forbidden love affair with Hilary would mark the character's first major love story and would also solidify the character as a viable romantic lead. Due to the chemistry between the characters, the pairing of Devon and Hilary quickly amassed a very active fan base and as well as critical acclaim which propelled them to supercouple status. James earned six Daytime Emmy Award nominations for Outstanding Supporting Actor in a Drama Series; he won the award in 2020. In 2025, the character made a crossover appearance on Beyond the Gates, the first in the serial's production.

The character is introduced in 2004 as a delinquent living out of group homes. The homeless teenager is fostered and eventually adopted by Drucilla Winters (Victoria Rowell) and her husband, Neil (Kristoff St. John). In 2006, Devon contracts meningitis and completely loses his hearing and he receives a cochlear implant to restore his hearing. Later Devon is implicated in the murder of Carmen Mesta (Marisa Ramirez). Fortunately his name is cleared when Jana Hawkes (Emily O'Brien) admits to the murder. In December 2006, Devon is officially adopted by Neil and Dru but his happiness is short-lived when Dru is presumed dead in April 2007. Later that year, Devon starts dating Lily's friend, Roxanne (Tatyana Ali). In 2008, Devon meets his "aunt" Tyra (Eva Marcille) for the first time and he learns that Tyra's adopted daughter, Ana (Jamia Simone Nash) is actually his biological half-sister, also abandoned by Yolanda.

In 2009, Neil and his new wife Karen Taylor (Nia Peeples) make plans to adopt Ana but those chances are destroyed when Neil cheats with Tyra—and Devon witnesses the affair. In May 2009, Devon meets his great-aunt Virginia (Della Reese) who reveals that Tyra is adopted and Devon disapproves when she starts dating Neil. However, Devon realizes his disdain for Tyra stems from the fact that he is attracted to her and after she splits with Neil, they end up sleeping together after he berates her for breaking up Neil's marriage. Roxanne finds them together and immediately dumps him while Tyra skips town with Ana. Devon and Roxy reconcile in October 2009.

After he graduates college in 2010, Devon takes a job as a photographer's assistant to support his music career. He lands a gig at Tucker McCall's label Resurrection Music producing with Noah Newman (Luke Kleintank). However, when Noah abandons him for another gig, Devon convinces Tucker to give him another chance which culminates with Tucker firing him. Fortunately, Tucker's estranged mother Katherine Chancellor (Jeanne Cooper) launches her own label and hires Devon to run it. When Katherine falls into a coma, it is revealed that Tucker is Devon's biological father. Devon rejects Tucker and Katherine as Yolanda (Debbi Morgan), now called Harmony, returns looking to make amends and explain her actions. Ana convinces Devon to forgive Yolanda, and try and connect with his new family. In 2012, Tucker and Harmony convince Devon to get another surgery to improve his hearing. Devon befriends Abby Newman (Marcy Rylan) who invests in his label as he produces for Angelina Veneziano (Diana DeGarmo). Devon offers her a record contract, but Angelina instead goes to California and Devon closes down his label and joins the marketing team at Jabot Cosmetics. In 2013, Tucker offers Devon a position at his record label but Devon turns it down because it would keep him away from his family and Roxy is furious that Devon considered taking the position without consulting her. Katherine passes away and Devon is shocked when he inherits the bulk of her billion dollar estate. Devon offers a million-dollar reward for Cordelia Abbott's killer and even funds a charity in her name. However, Devon's paranoia about his new found wealth leads to Roxy leaving him. Devon befriends Mason Wilder (Lamon Archey) and the reformed bad girl Hilary Curtis (Mishael Morgan) who tips him off about Mason stealing his identity after Devon gets arrested for destroying a hotel room in Las Vegas. Devon also defends Hilary against Lily's attacks.

In 2014, Devon buys the Genoa City Athletic Club, hires Lily and her husband Cane Ashby (Daniel Goddard) to run it. After Hilary rejects him, Devon has several flings, including the gold digger model Esmeralda (Briana Nicole Henry). Despite that, Devon is still attracted to Hilary and is furious to learn she is sleeping with Neil. Devon professes his love for Hilary and kisses Hilary the night before she marries Neil. Hilary rejects him, Devon reluctantly stands in as Neil's best man at the wedding. Devon drowns his sorrows in alcohol, getting Hilary's attention, and she urges him to forget about her. Devon admits his love for her and after several close moments, Devon decides to leave town. Though she doesn't want to hurt Neil, Hilary admits her feelings for Devon and they grow closer after they are stranded on the side of the road over night. Devon later agrees to a date with Abby (Melissa Ordway) hoping to get Cane and Lily off his back just as Hilary is ready to make a decision about their future. Hilary finally professes her love for Devon and they agree to tell Neil the truth just as Neil lands in the hospital after being electrocuted and left blind. Because Hilary refuses to leave Neil until he recovers, Devon and Hilary give in to temptation and begin an affair. They are later discovered by Cane who orders them to end it immediately. However, they continue seeing each other in secret only to be caught by Cane's father Colin Atkinson (Tristan Rogers) who blackmails Devon into paying him off in exchange for his silence. Colin later demands more money so he can help Jill acquire Chancellor Industries from Victor Newman. Cane neutralizes Colin and Devon gives the money directly to Jill and makes her promise to cut Colin out of the company.

Devon wants to wait for Neil to adjust to the news that his condition isn't treatable, only for Neil to confront them when they are on a plane trip to Chicago looking for office space for Chancellor. The plane later crashes leaving the group stranded in a blizzard and they are eventually rescued. Devon is devastated when Hilary announces that she faked her love for Devon to avenge her mother's death. In March 2015, during a drunken binge, Neil causes a car accident that leads to district attorney Christine Blair (Lauralee Bell) and police chief Paul Williams (Doug Davidson) losing their unborn child and to keep Neil out of prison, Devon immediately contacts Leslie to represent him. Devon is shocked when Hilary blackmails ADA Winston Mobley (Ryan Caltagirone) into giving Neil a suspended sentence. Hilary finally comes clean about her schemes and tells Devon she is still in love with him and she only left him so he could salvage a relationship with Neil.
