Mary Brooke, died after 1535, was the daughter of Thomas Brooke, 8th baron Cobham (d. July 19, 1529) and, probably, his first wife, Dorothy Heydon. She is said to have been the mistress of George Neville, 3rd baron Bervavenny (c.1469-June 13, 1535) during his marriage to his third wife. She became his fourth wife sometime before January 24, 1530, when he settled estates on her. She was pregnant in the spring of 1535, shortly before his death. It is unclear what happened to her or to the child.
