Eve Lucinda "Lucy" Fleming (born 15 May 1947) is a British actress.

She is the daughter of the actress Celia Johnson and the writer Lt-Col Robert Peter Fleming (the brother of James Bond author Ian Fleming ). Since 1997, Ian Fleming's two nieces, Lucy and her sister Kate Fleming, have controlled Ian Fleming Publications.

Lucy Fleming is best known for her role as Jenny Richards in the BBC post-apocalyptic drama series Survivors, which originally aired from 1975–1977, with Jenny the only character to appear in both the first and last episodes of the show. Her numerous credits in other British television series include The Avengers, Smiley's People, Mr. Bean, the regular role of Jo in Cold Warrior, the first Helen Wycliffe in Wycliffe, A Dance to the Music of Time, Heartbeat, Rosemary & Thyme and Kingdom. More recently she has appeared on the long running radio soap opera The Archers as Miranda, the depressed wife of minor tycoon Justin Elliot, who is played by her "real world" husband.

Fleming has been married twice; first to Joseph William Peter Laycock (b. July 1938) from 1971 to 1980, by whom she had a daughter Flora Laycock (b. March 1972), and two sons Robert Laycock (b. June 1973) and Diggory Laycock (b. December 1975).. Her husband and her daughter, Flora, drowned on 14 December 1980 in a boating accident on the Thames. She married the actor Simon Williams in 1986.

Fleming spent part of her childhood growing up in New Zealand: "My parents packed me off to some friends in New Zealand when I was 16, hoping I would grow up a little and perhaps change my mind about acting. I was quite a tomboy. I ended up at the Bay of Islands, which was just the most beautiful place in the world. I was meant to be looking after the friends' little boy, but I didn't have a clue, and I don't recall doing much of that at all. I loved the country, though."
