Winifred Fortescue (7 February 1888 – 9 April 1951) was a British writer and actress.
The wife of Sir John Fortescue, librarian and archivist at Windsor Castle and reputed British Army historian, she became formally styled Winifred, Lady Fortescue, when he was knighted in 1926.
She was mainly educated at home, having "outgrown her strength," but when she was 16 her doctor informed her mother that she was suffering from "intellectual starvation."
She gave up her stage career and took up an interior decorating and dress designing business until illness forced her to give it up.
She then began writing for Punch, the Daily Chronicle and The Evening News, and then started a Women's Page for the Morning Post.
