Mayo is a British television detective fiction-comedy series, adapted from the Gil Mayo Mysteries series books by Marjorie Eccles, first broadcast on BBC One on 12 March 2006. The eight-part series, produced by BBC Birmingham, starred Alistair McGowan as the titular character, alongside Jessica Oyelowo, Huw Rhys and Louise Brealey. The series was developed by Simon Booker, and directed by Metin Huseyin, Jonathan Fox Bassett and Fraser MacDonald.

The series was filmed on location in and around Leamington Spa. Each of the eight episodes were based upon one of Eccles' novels, aside from the final episode, which was an original story for television by Joe Ainsworth. McGowan provided additional script dialogue for all eight episodes, and was also heavily involved in helping produce the series. Notable guest stars throughout the series run included former Doctor Who Sylvester McCoy and actress and singer Paloma Faith.
