Ages Of US Presidents

The tables on this page show the complete list of US Presidents, listed by their age upon taking office.

Donald J. Trump is the oldest man ever elected to the office of President of the United States. Trump was born on June 14, 1946. When he was sworn in as president on January 20, 2017, he was 70 years, 7 months and 6 days old. Trump’s age today is 72 years, 4 months, 6 days.

Trump supplants the previous oldest president, Ronald Reagan, who was 69 years, 11 months and 14 days old when he was first sworn in on January 20, 1981.

John F. Kennedy is the youngest-ever elected president, aged 43.

However, Theodore Roosevelt is the youngest person to ever become president. He was 42 when he succeeded to the presidency, following the assassination of William McKinley.

The first table below summarises the most common questions asked about presidential ages. The second table lists all 44 presidents by their age upon taking office. Whilst Trump is the 45th president, he is only the 44th man to hold the office because Grover Cleveland held two non-consecutive terms and is counted as the 22nd and the 24th president.
