List of presidents of the United States who owned slaves

Slavery was legal in the United States from its beginning as a nation, having been practiced in North America from early colonial days. The Thirteenth Amendment to the United States Constitution formally abolished slavery in 1865, immediately after the end of the American Civil War.

Twelve U.S. presidents owned slaves at some point in their lives; of these, eight owned slaves while in office. Ten of the first twelve American presidents owned slaves, the only exceptions being John Adams and his son John Quincy Adams, neither of whom approved of slavery. George Washington was the first president who owned slaves, including while he was president. Zachary Taylor was the last one who owned slaves during his presidency, and Ulysses S. Grant was the last president to have owned slaves at some point in his life. Of these presidents who owned slaves, Thomas Jefferson owned the most, with 600+ slaves, followed closely by George Washington. Woodrow Wilson was the last president born into a household with slave labor, though the Civil War concluded during his childhood.
