Audubon Swamp Garden is a 60-acre cypress and tupelo swamp on the grounds of Magnolia Plantation near Charleston, South Carolina. At one time, the swamp served as a reservoir for the plantation's rice cultivation. Today, the swamp garden includes native flora but also non-native, exotic plantings and is home to herons, ibis, turtles, otters, alligators, and other wildlife.

The swamp garden is named for the ornithologist and artist John James Audubon, who visited the plantation before the Civil War and is said to have collected waterfowl specimans there as models for his paintings. More recently, director Wes Craven made use of the site while filming the 1982 horror movie Swamp Thing.
