Steven Moffat (born 1961 in Paisley, Scotland, UK) is a respected British comedy/drama writer who has contributed to television series since the late 1980s.

After initially working as a teacher, his first work on television was for the children's drama series Press Gang, starring Julia Sawalha in 1989, which he also co-created. The series was immensely successful and ran for four years on ITV, with Moffat penning all of the forty-three episodes.

He later moved onto writing jobs on series such as Murder Most Horrid starring Dawn French, and created two of his own sitcoms, BBC One's Chalk and BBC Two's Joking Apart. As is traditional for many of those in the British sitcom world, he has contributed to the bi-annual Comic Relief charity telethon nights, including writing the script for the science-fiction parody Doctor Who and the Curse of Fatal Death in 1999.

In 2000 he created and wrote the sitcom Coupling for BBC Two. The series proved to be highly successful and as of 2004 has produced four seasons and twenty-eight episodes, all written by Moffat. He also wrote the original, unbroadcast, pilot episode for the American version of the same series, in 2003, although this was less successful and was cancelled after just four episodes on the NBC network.

In March 2004, he was announced as one of the writers of the forthcoming new series of the science-fiction classic Doctor Who for BBC One. Other current projects include developing his own, currently untitled, science-fiction series for the BBC and a film script, Me Again.
