The House of La Trémoïlle (Maison de La Trémoille in French) was a French noble family from Poitou whose name comes from the village La Trimouille in the départment of Vienne. This family has been known since the middle of the 11th century, and since the 14th century its members have been conspicuous in French history as nobles, military leaders and crusaders, and influential as political leaders, diplomats, Huguenots and courtiers. The male line of the family died out in 1933, while female line heirs of the last duke have kept the La Trémoïlle surname alive in Belgium.
