The President's House, also known as the John Maclean House, or simply the Maclean House, in Princeton, Mercer County, New Jersey, United States, was built to serve as the home of the President of the College of New Jersey, which later became Princeton University. It was completed in 1756, the same year as Nassau Hall. John Witherspoon lived here from 1768 through 1779, during which time he served as a delegate to the Continental Congress and signed the Declaration of Independence. George Washington occupied Maclean House in January 1777, during the Battle of Princeton and in 1783 while Congress met in Nassau Hall.
