Mattapax is a historic home located at Stevensville, Queen Anne's County, Maryland, United States. It is a 1 1⁄2-story brick house, three bays wide, and one room deep, with flush brick chimneys at either end of a pitched gable roof built about 1760. In 1949 a restoration resulted in the construction of a brick wing to replace an earlier frame wing. Also on the property are a frame cottage, a large horse barn, and a frame wagon shed.
It was listed on the National Register of Historic Places in 1998.
