Flint Ridge State Memorial is a Native American flint quarry located in Hopewell Township, Licking County, Ohio, about three miles 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.[2][3]

Flint Ridge was an important source of flint and Native Americans extracted the flint from hundreds of quarries along the ridge.[4] This "Ohio Flint" was traded across the eastern United States and has been found as far west as the Rocky Mountains and south around the Gulf of Mexico.[5]
