Fosbury House is a Grade II listed country house northwest of the village of Fosbury in Wiltshire, England, about 11 miles (18 km) southeast of Marlborough.

The mansion was built about 1800, in limestone ashlar with a hipped tiled roof, and has three storeys.

The three-bay front has a half-round Ionic portico and a pedimented gable.

[3][1] The house was recorded as Grade II listed in 1986,[1] as was the brick and flint kitchen garden wall at the rear, which has piers with urn finials and cast-iron gates.

In 2005, Robert Hesketh, son of Colonel Roger Fleetwood-Hesketh, Conservative MP for Southport, died from "a cocktail of alcohol, heroin and cocaine" at an 18th birthday party there.
