Cleopatra Mary Palmer (née Sylvestre; 19 April 1945 – 20 September 2024), known professionally as Cleo Sylvestre, was a British actress. She was the first black woman ever to play a leading role at the National Theatre in London, and the first woman to record with The Rolling Stones.

Sylvestre was brought up in Euston, north London, by her mother, Laureen Sylvestre (née Goodare), a cabaret artist at the Shim Sham Club in Wardour Street, who was born in Yorkshire in 1911. Laureen was of mixed English and African' heritage, and married Owen Oscar Sylvestre, from Trinidad, in 1944. Owen was a Flight Sergeant in the Air Force and had been awarded the Distinguished Flying Medal; he and Laureen divorced in 1955. Sylvestre always understood Owen to be her father; her daughter Zoë discovered many years later - whilst working in Sierra Leone - that her biological father was Ben Lewis, a lawyer from Sierra Leone whom the family called Uncle Ben, and that she had 15 half-siblings. Aged eight, she made her film debut in Johnny on the Run.
