The Merrill-Poor House is a historic house and estate on Maine State Route 120 northeast of the village center of Andover, Maine. With construction dating to the late 1780s, the main house exemplifies the evolution of a frontier property. It is also significant as the birthplace of financier John A. Poor (1808-1871) and financial analyst Henry Varnum Poor (1812-1905), the latter of whom was responsible for its transformation into a summer estate in the late 19th century.
