Cathy Dennis (born Catherine Roseanne Dennis, 25 March 1970, Norwich, England) is a British dance-oriented pop singer-songwriter, record producer and actress. After a moderately successful international solo career, Dennis later received great success as a writer of pop songs, scoring 8 UK number ones and winning five Ivor Novello Awards.
As a teenager she was spotted recording Stevie Wonder-influenced demos at The Kitchen in Norwich with her father (himself an experienced musician and local restaurateur) on piano. At the time she was working for Norwich Union. Simon Fuller signed her to his 19 Management company (with whom she is still signed) and to label Polydor at aged 17, and this began a career-long association with the impresario that has seen Dennis provide songs for many Fuller-related artists and projects.
In 2004, Dennis was listed 66th in the Q Magazine list of the top 100 most influential people in music and in 2006 she won the UK music industry's Woman of the Year Award.
