Louisa MacGregor Rix (born 2 February 1955) is a British former actress of theatre, film and television, and interior designer.
She is perhaps best known for her role as "Mum" in the BBC sketch series, Harry Enfield & Chums, and its spin-off film, Kevin and Perry Go Large.
Rix gained early theatre experience at the Nottingham Playhouse while Richard Eyre was the artistic director, and in Peter Cheeseman's company at Stoke-on-Trent.
Her subsequent West End appearances included roles in How the Other Half Loves and Man of the Moment by Alan Ayckbourn; The Pocket Dream by Sandi Toksvig & Elly Brewer; and Whose Life is it Anyway?
She played the vocally-challenged night club singer Melody Lane in a feature-length Coronation Street special with the QEII as the location.
