Anne Beauchamp, 16th Countess of Warwick (13 July 1426 – 20 September 1492) was an important late medieval English noblewoman.

Anne Beauchamp's husband, Richard, was the grandson of Lady Joan Beaufort, Countess of Westmorland, sister of the Duke's late father.

[8] Her elder daughter, Lady Isabel, married George, Duke of Clarence, the younger brother of King Edward IV of England.

[9] Her younger daughter, Lady Anne Neville, was married to Edward of Westminster, the only son of Lancastrian King Henry VI.

[8] Anne is known to have passed an illustrated Book of Hours to her daughter, which had been commissioned by Richard Beauchamp, 13th Earl of Warwick.

A more sympathetic portrayal of the Countess of Warwick is in the novel The Sunne in Splendour by Sharon Kay Penman, and a maternal view of her is observed in The Reluctant Queen by Jean Plaidy.

[citation needed] Novelist Sandra Worth represents the Countess as her husband's conscience in her five novels about the Wars of the Roses.
