Montebrier is a historic plantation house in Brierfield, Alabama, United States. The 1 1/2-story frame structure was built circa 1853 by S.W. Mahan in a Gothic Revival cottage orné style. The house is notable for its use of lightly arched porch supports and wide eaves that may show the influence of Andrew Jackson Downing's The Architecture of Country Houses. It currently remains in the Mahan family as a private residence and was added to the National Register of Historic Places on April 2, 1973.
