The Larches is a historic house at 22 Larch Road in Cambridge, Massachusetts. This 2+1⁄2-story wood-frame house was built c. 1808, and originally stood on one of the last of Cambridge's large Brattle Street estates to be subdivided. It was moved to its present location in 1915, at which time it underwent renovations and alterations designed by Alexander Wadsworth Longfellow Jr. The building's interior and exterior both retain significant Federal style detailing. The house was built by William Gray, a Salem merchant, as a summer house. Twentieth century owners included composer Randall Thompson.
