The Loring–Greenough House is the last surviving 18th century residence in Sumner Hill, a historic section of Jamaica Plain, Massachusetts, a neighborhood of Boston.

This mid-Georgian mansion was built as a country residence and farmstead in 1760 for wealthy British naval officer Commodore Joshua Loring[2] on the original site of John Polley's estate established in the 1650s.

The house was confiscated by colonial forces and in 1776 served as a headquarters for General Nathanael Greene and, soon after, a hospital for Continental Army soldiers following the Battle of Bunker Hill.

In 1780, the house was sold to Isaac Sears, the rebel leader from New York, and was then purchased in 1784 by Ann Doane, a rich widow, who soon after married David Stoddard Greenough.

The property is fenced and gated; the public is invited to enjoy the grounds during daylight hours, and to attend events inside and outside the House throughout the year.
