Theobald III (French: Thibaut; 13 May 1179 – 24 May 1201) was Count of Champagne from 1197 to his death. He was designated heir by his older brother Henry II when the latter went to the Holy Land on the Third Crusade, and succeeded him upon his death. He cooperated closely with his uncle and suzerain King Philip II of France. He died young, and was succeeded by a posthumous son, Theobald IV, while his widow, Blanche of Navarre, ruled as regent.
