Independent

George Washington (1789–1797) is currently the only president to have been elected without any official endorsement by a political party. Generally speaking, Washington's policies reflected a moderate Federalist agenda. He governed for 8 years in total.

John Tyler and Andrew Johnson were effectively independent for part of their terms but since they were also members of the Whig and Democratic Party, respectively, for parts of their term they are traditionally counted as members of that party.
