Henry Holland, 3rd Duke of Exeter (27 June 1430 – September 1475) was a Lancastrian leader during the English Wars of the Roses. He was the only son of John Holland, 2nd Duke of Exeter, and his first wife, Lady Anne Stafford. His maternal grandparents were Edmund Stafford, 5th Earl of Stafford, and Anne of Gloucester.
He inherited the Dukedom of Exeter when his father died in 1447. A great-grandson of John of Gaunt, he might have had a plausible claim to the throne after the death of Henry VI. However, he was cruel, savagely temperamental and unpredictable, and so had little support.
Exeter was for a time Constable of the Tower of London, and afterwards the rack there came to be called "the Duke of Exeter's daughter".
In 1447 he married Anne, the eight-year-old daughter of Richard of York. However, in the Wars of the Roses, he remained loyal to Henry VI against the Yorkists. He was imprisoned at Wallingford Castle when York briefly seized power after the First Battle of St Albans in 1455. He was a commander at the Lancastrian victories at the Wakefield in 1460 and the Second Battle of St Albans in 1461, and in the decisive defeat at Towton in 1461. He fled to Scotland after the battle, and then joined Queen Margaret in her exile in France. He was attainted in 1461, and his estates were given to his wife, who separated from him in 1464. During the brief period of Henry VI's restoration he was able to regain many of his estates and posts.
