Percy Haswell (30 April 1871 – 14 June 1945), frequently billed as Miss Percy Haswell or Mrs. George Fawcett to clarify her gender, was an American stage and film actress.
Percy Haswell was born in Austin, Texas, the daughter of George Tyler Haswell, a politician and businessman, and Caroline Dalton. She was educated in Washington, D.C., and while still a child she first appeared on the stage in March 1885. She appeared with the Lafayette Square Theatre in Washington and acted in New York City at Augustin Daly's Theatre. Her stage career also included appearances in Baltimore, Boston, Buffalo, Toronto and other locales, as well as New York, where she first appeared on Broadway in 1898, returning periodically through 1932.
On 2 June 1895, at Bridgeport, Connecticut, she married to fellow actor George Fawcett. In 1901 at Baltimore she formed the Percy Haswell Stock Company but later took a secondary role to her husband, her company forming a constituent part of the George Fawcett Stock Company. In 1925, she directed the Broadway play, The Complex. She also appeared in two silent films in 1919 and one in 1929.
She died in Nantucket, Massachusetts, the mother of one daughter.
Writer Fulton Oursler commented, in describing his infatuation with her, that she was "so blonde, so blue-eyed, with voice so throaty sweet. She was a lass from Austin, Texas, but to me she seemed to belong to some other world altogether. She was my first Rosalind, and Juliet, and Ophelia, and a dozen other heroines, sacred and profane."
