Clifton House is a historic building located at 473 Bethlehem Pike in Fort Washington, Pennsylvania. During the autumn of 1777, Washington's Continental Army spent six weeks camped at nearby Whitemarsh. Colonels Clement Biddle (the "Quaker General" and member of one of Philadelphia's prominent families) and Stephen Moylan, and General George Wheedon, were quartered here during the encampment. The house that currently stands on the property was built in 1801. At the time of the American Revolution, it was known as the Sandy Run Inn.
