Martine McCutcheon (born Martine Kimberley Sherri Ponting) is an English singer, television personality and Laurence Olivier Award-winning actress. McCutcheon had minor success as one third of the pop group Milan in the early 1990s; however, it was her role as Tiffany Mitchell in BBC's EastEnders that made her a household name in the UK in 1995.

McCutcheon quit the serial at the end of 1998 to embark on a pop career, this time as a solo artist. She had international success, reaching #1 in 5 countries with her debut single "Perfect Moment".

She released three albums to varying degrees of success, but her pop career stalled due to the poor reception of her third album in 2002. She has since appeared in various television programmes, in films such as Love Actually, and on stage in My Fair Lady, where her portrayal of Eliza Doolittle won her a Laurence Olivier Award in 2002.

McCutcheon's personal life has been the subject of much press speculation in the UK and she has been romantically linked to numerous celebrities and sports personalities. She released her autobiography, Who Does She Think She Is? in 2000.
