Kevin Webster is a fictional character from the British ITV soap opera Coronation Street. Portrayed by Michael Le Vell, the character first appeared on-screen during the episode airing on 19 October 1983. Le Vell was suspended from the soap in February 2013 due to allegations of sexual offences, with scenes he had already filmed cut from broadcast. Le Vell was found not guilty of all charges in September 2013, and briefly returned in early 2014, before taking another 3-month break from the show and returning once again.

Kevin is protective of his two daughters Rosie Webster (Emma Collinge, Helen Flanagan) and Sophie Webster (Ashleigh Middleton, Emma Woodward, Brooke Vincent) along with their mother Sally Webster (Sally Dynevor). His notable storylines have originally centered on his on-and-off romantic chemistry with Sally that involved two separate marriages, the first of which ended after he had a tryst with local neighbour Natalie Horrocks (Denise Welch); and then his second marriage with Sally collapsed beyond repair after he embarked on a long-running affair with fellow resident Molly Dobbs (Vicky Binns) that ultimately led to him fathering her son Jack (Kyran Bowes) after her untimely death in a tram crash amid the show's 50th anniversary live episode. His other major plotlines have included a short-lived marriage with his second spouse Alison Wakefield (Naomi Radcliffe); having separate romances with Sally's old rivals Jenny Bradley (Sally Ann Matthews) and Anna Windass (Debbie Rush) on respective occasions; getting involved in a feud with Anna's villainous rapist Pat Phelan (Connor McIntyre); having to care for Jack after he was diagnosed with sepsis that caused the latter to require foot amputation before helping him with treatment; getting remarried to Abi Franklin (Sally Carman); and being diagnosed with testicular cancer.

Actor Michael Le Vell auditioned for the role and landed the part after he had played another character called Neil Grimshaw, a newspaper delivery boy who worked at The Kabin.

Kevin is very much a family man and looks out for them. ITV publicity say of the character: "A no-nonsense garage mechanic who likes an uncomplicated life and his tea on the table when he comes home from work.". In the book Life in The Street by Graeme Kay, Kevin is described as a "very cheerful yet cautious" character.

Kevin is the son of Bill (Peter Armitage) and Alison Webster. Kevin's mother died of cancer when he was just 15 years old and this experience traumatised him. He first appears in 1983, as an apprentice mechanic working for Brian Tilsley (Chris Quinten). His father Bill and his younger sister, Debbie (Sue Devaney), later join him. Initially his life consists of working by day and drinking with friends Terry Duckworth (Nigel Pivaro) and Curly Watts (Kevin Kennedy) in the evening. He dates Mandie Whitworth, a friend of Terry's girlfriend, and Michelle Robinson and meets his long-term love interest, Sally Seddon (Sally Dynevor), in 1986 and they later marry. The Websters buy 13 Coronation Street from Hilda Ogden (Jean Alexander) after she leaves to work as a doctor's housekeeper.

The characters of Kevin and Sally had a lack of storylines in their first years on the show but received a boost when Brian Park became executive producer. The Independent reports him as saying "Kevin and Sally Webster had years of washing their hands and eating baked beans on toast. Michael Le Vell and Sally Dynevor (then Whittaker) were then given great storylines, including his affair with Natalie, Sally's catfight with her when she found out and the subsequent divorce".

Kevin spends his early years in the show with Sally Seddon. They marry and have two daughters, Rosie (Helen Flanagan) and Sophie (Brooke Vincent). While Sally is away nursing her sick mother, Kevin has an affair with Natalie Horrocks (Denise Welch), mother of his business partner. Natalie has no compunction about seducing a married man. Sally angrily confronts Natalie when she learns of the affair. Kevin and Sally divorce due to the affair and Kevin moves in with Natalie. However, he is unhappy and ends the relationship to return to Sally.

Sally and Kevin reconcile, partly for the girls' sake. However, Sally is seduced by Greg Kelly (Stephen Billington). Kevin throws her out when he learns of the affair. Greg uses Sally's money (inherited from her mother) and abuses her. The affair ends but Kevin refuses to take her back, marrying Alison Wakefield (Naomi Radcliffe) instead. The night before the wedding, Kevin and Sally sleep together for old times' sake. This secret assignation comes out, on the day Sally is to marry Danny Hargreaves (Richard Standing). Danny calls their wedding off, angry that she had cheated on him and then lied about it as Sally blames Kevin for ruining the wedding.
