Luke Morgan is a fictional character from the British Channel 4 soap opera Hollyoaks, played by Gary Lucy. He was introduced by the show's creator Phil Redmond as part of the Morgan family, and made his first appearance on 25 March 1999. The character was involved in a male rape storyline, which was branded "groundbreaking" and met with controversy. Lucy opted to leave the role in 2001 after two years, although he returned for two episodes in August 2002. The character's reintroduction was announced on 21 May 2017 and he returned on 24 July. Lucy took a break from the series in 2018 to appear in a play. The character made a few brief appearances throughout 2019 before he returned permanently in August. Luke was killed off in 2022, with his final scenes airing on 9 June 2022. He returned briefly in 2023 as a vision to his former fiancée Cindy Cunningham (Stephanie Waring).

Warm, good-looking, charismatic and bursting with energy, Luke Morgan is the very definition of a "glass half-full". To everybody around him, Luke's the happiest guy in the village, buzzing with positivity and always with big plans for the future. Ex-footballer Luke's got an endearing enthusiasm, which makes you want to believe in him as much as he believes in himself. Everybody knows that Luke is terrific on a night out, but few realise how hard it is for him to keep control...

— An excerpt from Luke's profile on the official Hollyoaks website.

The Mirror described him as "sullen face but loveable". Luke has been described as a "heart-throb" and a "hunk" by the Daily Record.

Luke was bullied by Mark Gibbs and his friends for a while due to a football team rivalry. When Luke finally stood up to him Mark was incensed and he and his friends beat Luke up badly. When Luke tried to fight back, Mark raped Luke to belittle and devastate him. Hollyoaks creator Phil Redmond defended criticism and said the storyline "aimed to tackle one of the last great social taboos responsibly". In the lead up to the attack producers worked closely with rape-related support groups to help make the storyline as realistic as possible. On the storyline Lucy said "When they first told me about the storyline I was dubious as to whether or not I should take it. Firstly because I was so young and secondly it hadn't been touched before so no-one knew how the public and press would take it. After thinking about it and doing research behind it I thought it was definitely a subject worth approaching. So we did it and reaped the rewards. I feel very lucky." On why she wanted to tackle the subject series producer Jo Hallows said "The message is about banishing taboos – telling people it's OK to talk and there are people who can help. If this episode helps one person it will have been a worthwhile exercise." Keith Greenaway, coordinator of Central Birmingham Victim Support welcomed the decision saying "we can show victims it is not something to be ashamed of and it wasn't their fault".

Hallows directed the episode and later recalled the episode meant a lot to her. Hallows told Wendy Granditer from Inside Soap that production originally worried that Lucy would not be able to cope with tackling such a difficult storyline. She reasoned that Lucy had not previously been given such a "heavy" story. Hallows admitted she was wrong because Lucy "did fantastically well" and noted his success at the British Soap Awards. Following the end of the storyline, Luke began to struggle with depression, which led to the character attempting suicide.

On 21 May 2017, it was reported that Lucy had agreed to reprise the role after an absence of fifteen years and had signed an eighteen-month contract. A show spokesperson confirmed the news to Digital Spy but refused to comment any further. Sarah James (Digital Spy) praised the news and said she was looking forward to his return.

"Luke is definitely not the same person and it is definitely not for the better. Hopefully it'll be make for good viewing though."
