List of United States Presidents by age

This is a list of United States Presidents by age. This table can be sorted to display United States Presidents by name, order of office, date of birth, age at inauguration, length of retirement, or lifespan. Age at inauguration is determined by the day a president assumed office, not the day of the election.

Two measures of longevity are given; this is to allow for the differing number of leap days occurring within the life of each President. The first figure is the number of days between date of birth and date of death, allowing for leap days; in parentheses the same period given in years and days, with the years being the number of whole years the President lived, and the days being the remaining number of days after his last birthday. Where the president in question is still living, the longevity is calculated up to .
