Hains Point is located at the southern tip of East Potomac Park between the main branch of the Potomac River and the Washington Channel in southwest Washington, D.C. The land on which the park is located is sometimes described as a peninsula but is actually an island: the Washington Channel connects with the Tidal Basin north of the park and the Jefferson Memorial. The island is artificial: it was built up from Potomac dredging material from 1880 to 1892.
