Montpelier Mansion, sometimes known as the Snowden-Long House, New Birmingham, or simply Montpelier, is a five-part, Georgian style plantation house located south of Laurel in Prince George's County, Maryland. It was most likely constructed between 1781 and 1785. Built by Major Thomas Snowden and his wife Anne, the house is now a National Historic Landmark operated as a house museum. The home and 70 acres (28 ha) remain of what was once a slave plantation of about 9,000 acres (3,600 ha).

It was declared a National Historic Landmark in 1970, primarily for its architecture.
