Pamela Sydney Frankau (3 January 1908 – 8 June 1967) was a popular English novelist from a prominent artistic and literary family.

After serving in World War II, she was married for several years to an American naval officer, but returned to England and resumed her writing career.

During the Second World War, she worked for the BBC] the Ministry of Food and then with the Auxiliary Territorial Service, where she began a lesbian affair with fellow officer Marjorie Vernon Whitefoord, who sponsored Frankau's conversion to Roman Catholicism in 1942.

In 1946, their only child, Anthony Marshall Dill, died in infancy, resulting from complications due to premature birth.

After a five-year battle with the disease, Frankau died aged 59 at the Hampstead home she had shared with Margaret Webster.

Colonel Blessington, Frankau's final novel was edited by her cousin, writer Diana Raymond; it was posthumously published in 1968.
