Todd Carty, also known as Todd John Jennings (born Todd Robert Carty; 31 August 1963), is an English actor and director who has grown up on television screens in a variety of roles. His stage appearances have ranged from serious drama to pantomime, and he has worked on radio plays, voiceovers, commercials, narrations and films. He is best known for TV roles as Tucker Jenkins in Grange Hill (1978–1982) and Tucker's Luck (1983–1985), Mark Fowler in EastEnders (1990–2003), and PC Gabriel Kent in The Bill (2003–2005).

Carty was born in Willesden, London, as Todd R. Carty to an unmarried Irish mother, Margaret M. Carty, from Limerick. In 1972 Margaret married Thomas Jennings, who later adopted Carty and legally changed his name to Todd John Jennings. Through his mother, Carty is a dual citizen of the United Kingdom and Republic of Ireland. He grew up in Kilburn, West Hampstead and Harrow on the Hill, London. He has two younger sisters named Billie Joe and Bobby Sue, who respectively work as a lawyer and a teacher. Carty was educated at the Phildene Stage School, a co-educational independent school in Chiswick in west London.

Carty's first television appearance in the UK was in an advertisement for Woolworths, aged four. He also had other advertising and Public Information Film roles, including one with Doctor Who actor Jon Pertwee for the Green Cross Code.

Carty made his first professional stage appearance at the New London Theatre, Drury Lane, London, as the young Lionel in Lionel Bart's autobiographical musical Lionel!. However, his career in his youth was mostly defined by his television role as Tucker Jenkins in the BBC children's drama Grange Hill (1978–1982) and the spin-off series Tucker's Luck (1983–1985).

During the 1970s and 1980s, Carty also appeared in Z-Cars (1976), Our Mutual Friend, Drummer, and Headmaster, all for the BBC; and, for German TV, Focus on Britain and The Idle Bunch. His film work included Please Sir! (1971) and Professor Popper's Problem (1974). In 1983, he landed the role of Oswyn in the fantasy film Krull opposite Kenneth Marshall, Lysette Anthony, Liam Neeson and Alun Armstrong, among others.

Carty took over the role of original character Mark Fowler in the BBC One soap opera EastEnders in 1990, following the death of the original actor, David Scarboro. Carty played the role for 13 years, becoming one of the longer-running male cast members. In July 2002, the BBC announced Mark Fowler was being written out of the serial, a mutual decision between the producers and Carty. Executive producer Louise Berridge said Carty had made a "fantastic contribution" to the soap and Mark had been a "pivotal figure", but the character had finally run its course: "Todd and I have discussed this at some length and agreed that it was time for Mark to hang up his leather jacket for the last time. We will all miss Todd, who is one of our best-loved actors, and wish him every success in the future." Carty made his final appearance as Mark in February 2003, riding out of the Square on his motorbike and falling off. The character subsequently died off-screen in 2004.

After leaving EastEnders in 2003, Carty went on to play the villainous PC Gabriel Kent, in ITV's The Bill from 2003 to 2005. Carty has since revealed he broke his EastEnders contract a year earlier than planned to take on this new role.

In 2019, Carty shared his memories of playing Gabriel in an interview for The Bill Podcast.
