The Alligator Effigy Mound is an effigy mound in Granville, Ohio, United States. The mound is believed to have been built between AD 800 and 1200 by people of the Fort Ancient culture. The mound was likely a ceremonial site, as it was not used for burials.

Located on privately owned land, but accessible to the public, Alligator Mound is one of two extant effigy mounds known in the present-day state of Ohio, along with Serpent Mound in Adams County, Ohio. Effigy mounds were built more often by ancient indigenous peoples located in the areas of the present-day states of Illinois, Iowa, and Wisconsin than in the Ohio area, and many have survived there.

The site has been listed on the National Register of Historic Places since 1971. It is marked by an Ohio State Historical Marker, erected in 1998.
