William Malet (born before 1175–1215), feudal baron of Curry Mallet in Somerset, was one of the guarantors of Magna Carta. In 1190, he accompanied King Richard the Lionheart on third crusade. While still on crusade in 1191, he took part in the Siege of Acre. Upon returning to England, he served as Sheriff of Somerset and Dorset in 1209. The precise nature of his relationship to an earlier William Malet is unknown.
William Malet was one of the rebel barons who were heavily indebted to King John. It is believed that by 1214 he owed the king as much as £1333. In 1214 he entered into an agreement to serve with the king along with 10 knights and 20 other soldiers in exchange for the cancellation of his debts. However, the agreement broke down for an unknown reason and by 1215 he joined the rebellion.
William Malet seems to have died just a few months after Magna Carta was signed by King John.
