Alice Frederica Keppel (''née'' Edmonstone; 29 April 1868 – 11 September 1947) was a British society hostess and a long-time mistress of King Edward VII.
Keppel grew up at Duntreath Castle, the family seat of the Edmonstone baronets in Scotland. She was the youngest child of Sir William Edmonstone, 4th Baronet. In 1891 she married The Honourable George Keppel and they had two daughters. She became one of the best society hostesses of the Edwardian era. Her beauty, charm and discretion impressed London society and brought her to the attention of the future King Edward VII in 1898, whose mistress she remained till his death, lightening the dark moods of his later years, and allegedly held considerable influence.
