Langlade, Charles Michel de (1729–1801), a French-Canadian fur trader and a leader of Indian auxiliaries in the French and Indian War and the American Revolution. Langlade was born in what is now Mackinaw City, Michigan; his father was a French-Canadian fur trader, his mother an Ottawa Indian. He moved to the area that is now Green Bay, Wisconsin, and established a trading post there before joining the French colonial army in 1750. During the French and Indian War, Langlade's Indians helped defeat the British at Fort Duquesne in 1755.

After France lost the war, Langlade became a British subject. During the American Revolution, he led Indian's supporting the British. In recognition of his services, he was made superintendent of Indians and commander-in-chief of the Canadian militia, with headquarters at Green Bay. (Although officially part of the United States after the Revolutionary War, Wisconsin remained under British control until after the War of 1812.)
