• Source: List of presidents of the United States by age

In this list of presidents of the United States by age, the first table charts the age of each president of the United States at the time of presidential inauguration (first inauguration if elected to multiple and consecutive terms), upon leaving office, and at the time of death. Where the president is still living, their lifespan and post-presidency timespan are calculated through November 27, 2024.




Age of presidents



Article Two of the United States Constitution provides that U.S. presidents must be at least 35 years old at the time of taking office. The median age at inauguration of incoming U.S. presidents is 55 years. The youngest person to become U.S. president was Theodore Roosevelt, who, at age 42, succeeded to the office after the assassination of William McKinley. The oldest person inaugurated president is Joe Biden, at the age of 78.
Assassinated at age 46, John F. Kennedy was the youngest president at the end of his tenure, and his lifespan was the shortest of any president. The oldest president at the end of his tenure was Ronald Reagan at 77.
James K. Polk had the shortest retirement of any president, dying of cholera only 103 days after leaving office, at the age of 53 (the youngest president to die of natural causes). Jimmy Carter's retirement, currently 43 years, is the longest in American presidential history. Carter is the oldest of the six living U.S. presidents, the nation's longest-lived former president, and the first former president to reach the age of 100. The youngest living former president is Barack Obama, age 63.
