The Asa and Sylvester Abbot House is a historic rural two-family house at 15-17 Porter Road in Andover, Massachusetts. The house was built in the 1830s by Asa Abbot, a farmer and member of the locally prominent Abbot family. He left the house to his sons, Sylvester and Asa Albert Abbot, who farmed the surrounding land until the turn of the 20th century. The house was listed on the National Register of Historic Places in 1982, where it is incorrectly listed at 15-17 Andover Street.
