Old Mission is an unincorporated community within Peninsula Township, Grand Traverse County in the U.S. state of Michigan.
In the 1836 Treaty of Washington, the U.S. federal government agreed to provide local native tribes with both a mission and schools for their reservation. Henry Schoolcraft, the Indian agent representing the government, selected a natural harbor on the eastern shore of the peninsula in Grand Traverse Bay for the planned facilities. In 1838 the Presbyterian Board of Missions, sent the Reverend Peter Dougherty to establish the mission, now known as Old Mission, for which the peninsula would eventually become known.
The peninsula has extensive cherry orchards and vineyards. There are seven vineyards, but only five have tasting rooms. Because of the remoteness of the peninsula, wine tours take some planning. It is an American Viticultural Area and a center of the Michigan wine industry. See Old Mission Peninsula AVA.
The Old Mission Point Lighthouse is located at the northern terminus of M-37, at the tip of the Old Mission Peninsula, which juts 18 miles into Grand Traverse Bay.
