McGillivray Alexander (1759?–1793), a Creek Indian chief. During the era in which the British, Americans, and Spanish struggled for control of the American Southeast, he played one country against another in an effort to preserve Creek tribal lands.

McGillivray, son of a Scottish trader and a French-Indian woman, received his education from a tutor, who was related to his father. During the Revolutionary War he served as a British agent and led the Creeks in attacks on the frontier. Elected chief of the Creek nation, he signed a treaty with the Spanish in Florida in 1784 and, with supplies from them, continued fighting the American settlers. He was finally persuaded in 1790 to sign a treaty with the United States, but, when Creek boundaries still were violated, he renewed his alliance with the Spanish.
