Kate Radley (born 19 February 1967) was the keyboard player for the British post-rock and shoegaze band, Spiritualized, and was, for part of her tenure with the band, in a serious long-term relationship with the band's frontman and principal creative force, Jason Pierce. She was a member during their most fertile and readily-remembered period, which saw the release of the Lazer Guided Melodies, Pure Phase and Ladies and Gentlemen We Are Floating in Space albums, leaving the band in 1997.

She has been married to Richard Ashcroft, former frontman of The Verve, since 1995. The couple's first son, Sonny, was born on March 23, 2000. In 2004, their second son, Cassius, was born.
