Mackinaw City ( ) is a village in Emmet and Cheboygan counties in the U.S. state of Michigan. The population was 806 at the 2010 census; the population surges during the summer tourist season, including an influx of tourists and seasonal workers who serve in the shops, hotels and other recreational facilities there and in the surrounding region. Mackinaw City is at the northern tip (headland) of the Michigan's Lower Peninsula along the southern shore of the Straits of Mackinac. Across the straits lies the state's Upper Peninsula. These two land masses are physically connected by the Mackinac Bridge, which runs from Mackinaw City north to St. Ignace. Mackinaw City is also the primary base for ferry service to Mackinac Island, located to the northeast in the straits.
