Flint Ridge Ancient Quarries and Nature Preserve is a Native American flint quarry located in Hopewell Township, Licking County, Ohio, about 3 miles (5 km) north of Brownsville at the intersection of Brownsville Road and Flint Ridge Road.

Old quarry pits are visible, and a museum is located on the site.

Flint is a variety of quartz and the flint on the ridge is within the Vanport Limestone Member of the Allegheny Formation of Pennsylvanian age.
