Au Gres is a city in Arenac County in the U.S. state of Michigan. The population was 889 at the 2010 census.


French explorers named the location Point Au Gres, which stuck on map as late as 1828. Au Gres means "gritty stone" in the area, from which the river and the location takes it name. It was first settled in 1862 temporarily by workers on the Saginaw-Au Sable State Road when they reach the location. The first permanent settler was John Edward Bradley, who built the Bradley House in 1866. On August 8, 1867, the location, which was still a part of Bay County, was granted a post office with Bradley as the first postmaster. The post office was closed from March 2, 1874 until April 30, 1874.

The community was incorporated as a city in 1905.


According to the United States Census Bureau, the city has a total area of 2.33 square miles (6.03 km2), of which 2.23 square miles (5.78 km2) is land and 0.10 square miles (0.26 km2) is water.
