Maston House, also known as Cannon's Savannah, is a historic home located near Seaford, Sussex County, Delaware. It was built in 1727 and enlarged in 1733. It is a 1+1⁄2-story, single pile, brick structure with a gable roof in the "Resurrection Manor" style. As such, it resembles Maryland rather than Delaware houses. It has shed-roof dormers. The interior has wide floor boards and a narrow enclosed staircase winding around the chimney. It is one of Sussex County's oldest brick structures. A small frame addition from the 1970s is attached to the northern end.

It was added to the National Register of Historic Places in 1975.
