Anne Calthorpe, Countess of Sussex (died between 22 August 1579 and 28 March 1582) was an English courtier. She was the second wife of Henry Radcliffe, 2nd Earl of Sussex, who divorced her in 1555 on the grounds of her alleged bigamous marriage to Sir Edmund Knyvet, and her "unnatural and unkind" character.

She served as a lady-in-waiting in the household of Queen Consort Katherine Parr, the sixth wife of King Henry VIII, and shared her Reformed beliefs. She was implicated in the heresy of Anne Askew. In 1552, she was sent to the Tower of London for having practised sorcery and having made "treasonous prophecies".
