Lindsay Cooper (3 March 1951 – 18 September 2013) was an English bassoon and oboe player, composer and political activist. Best known for her work with the band Henry Cow, she was also a member of Comus, National Health, News from Babel and David Thomas and the Pedestrians. She collaborated with a number of musicians, including Chris Cutler and Sally Potter, and co-founded the Feminist Improvising Group. She wrote scores for film and TV and a song cycle Oh Moscow which was performed live around the world in 1987. She also recorded a number of solo albums, including Rags (1980), The Gold Diggers (1983) and Music For Other Occasions (1986).

Cooper was diagnosed with multiple sclerosis in the late 1970s, but did not disclose it to the musical community until the late 1990s when her illness prevented her from performing live. In September 2013, Cooper died from the illness at the age of 62, 15 years after her retirement.
