The Port Royal State Park is a state park and historic site in Adams, Tennessee. It features the historic community of Port Royal, one of the earliest colonial communities and trading posts in middle Tennessee.

Comprised of a measly 26 acres, the Port Royal State Park may be small but it is packed with history and things to see and do. Visitors can find the Red River running through the center of the park, as well as a covered bridge. The site also celebrates an annual Trail of Tears Commemorative event every October.

Visitors of the Port Royal State Park can enjoy picnicking, hiking, canoeing, and fishing at this day-use only park. This park is also a satellite of the Dunbar Cave State Park.
