# List of presidents of the United States by age

The first table below charts the age of each president of the United States at the time of their 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 March 6, 2025.

The median age at inauguration of incoming U.S. presidents is 55 years. The youngest person to become U.S. president was Theodore Roosevelt at age 42, who succeeded to the office after the assassination of William McKinley. The oldest person inaugurated president is Donald Trump, at age 78 years, 7 months, for his second term.

James K. Polk had the shortest retirement of any president, dying of cholera only 103 days after leaving office, at age 53 (the youngest president to die of natural causes).
