Lady Camilla Dorothy Godolphin Osborne (formerly Harris and Dempster; born 14 August 1950) is an English heiress. She is the only child of the 11th Duke of Leeds.

Lady Camilla Osborne was born on 14 August 1950 to John Osborne, 11th Duke of Leeds, and his second wife, Audrey Young. She grew up in Jersey, where her parents moved to avoid heavy taxes.

Her parents divorced in 1955 after her mother had an affair with a Guards officer. Her mother later remarried to Sir David Roland Walter Lawrence, 3rd Baronet.

Osborne's father married a third time in 1955 to Caroline Fleur Vatcher.

In 1963, at age 13, Osborne's father died without male issue. Due to the entail limiting the peerages to males only, she could not inherit her father's titles. The titles of her father passed to his cousin Sir D'Arcy Osborne, making him the 12th Duke of Leeds. When D'Arcy Osborne died in 1964 without issue, the Dukedom of Leeds and all the other peerages became extinct.

While she was not able to inherit the dukedom from her father, she did inherit money from his personal estate upon his death along with an annual allowance. In 1971 she inherited £1,000,000 (equivalent to £12,970,000 in 2016) from the family trust.

Osborne studied philosophy and English at Newcastle University, but left after a year.

Osborne married Julian Brownlow Harris and in 1972 gave birth to a daughter. The couple later divorced. In 1975 she became engaged to Christopher Moorsom, but later called off the engagement.
