List of autobiographies by presidents of the United States
Many presidents of the United States have written autobiographies about their presidencies and/or (some periods of) their life before their time in office. Some 19th-century U.S. presidents who wrote autobiographies are James Buchanan and Ulysses S. Grant, though Grant's autobiography is about his time as general during the American Civil War and not about his presidency.
