The Carpenter Homestead is a historic colonial American house and farm in Seekonk, Massachusetts.

Also known as Osamequin Farm, this 166-acre (67 ha) property includes a farmhouse and outbuildings whose construction history begins c. 1720.

The main house, now a 2+1⁄2-story wood-frame structure with a gable-over-hip roof and central chimney, was begun c. 1720, underwent numerous alterations and expansions, and was given a historically sensitive restoration in the 1940s under the direction of architect Edwin E. Cull.

The core portion of the main barn dates to the same time, with numerous additions in the intervening centuries, and also underwent restoration work in the 1940s.
