Mill Grove is a historic house and estate on Pawlings Road in Audubon, Pennsylvania. Built in the 1760s, it is notable as the first home in America of painter and naturalist John James Audubon (1785-1851), for whom the community is named. The 130-acre (53 ha) estate is now maintained as a museum and wildlife sanctuary by Montgomery County, and was designated a National Historic Landmark in 1989. The house serves as the educational center of the Pennsylvania chapter of the National Audubon Society, and is known as John James Audubon Center at Mill Grove.
