Susan Maureen Fleetwood (21 September 1944 – 29 September 1995) was a British stage, film and television actress, best known as a performer in classical theatre. She received popular attention in the television series Chandler & Co and The Buddha of Suburbia.
Fleetwood was born in St Andrews, Scotland, the daughter of Bridget Maureen (née Brereton) and John Joseph Kells Fleetwood, an RAF officer. She was the elder sister of musician and actor Mick Fleetwood. The service family was stationed in Egypt in the years before the Suez crisis and, afterwards, in Norway where John Fleetwood received a NATO appointment and where Susan received her first role as the Old Testament Joseph in a school play. On her return to England, she was encouraged to take up drama by a nun at a convent school, winning a scholarship to RADA at the age of sixteen. Her boyfriend at the time of her death was theatre director Sebastian Graham-Jones. She never married.
After training with RADA, where a student production won Fleetwood the Bancroft gold medal, in 1964 she joined the company of the Liverpool Everyman theatre, where her fellow student Terry Hands had been appointed director. When Hands moved to the RSC in 1967, she followed. In 1968 at Stratford she gave two commanding performances: in the relatively unpromising part of Cassandra in Troilus and Cressida and as Regan in Lear. In 1969, under the direction of Hands, she movingly doubled the parts Thaisa and Marina in Pericles.
