The president of the USA is the country's leader of state and administration and is indirectly chosen to a 4-year tenure by the American public via the Electoral College. The elected official is the head of the national government's executive authority and the commanding officer of the U.S. Armed Forces.

Since the ministry's inception in 1789, 45 individuals have held 46 presidencies. The first president, George Washington, was elected with the Electoral College's majority consent; one, Grover Cleveland, functioned 2 non-consecutive terms and is thus recorded as the twenty-second and twenty-fourth president of the USA, giving rise to the imbalance in the total count of presidents.

William Henry Harrison's presidency, which ended 31 days after he took office in 1841, was the smallest in American history. Franklin D. Roosevelt was the longest-serving president, serving nearly 12 years until death in the middle of his four-year term in 1945. He is the first President of the United States to have worked over 2 terms. Since the passage of the Twenty-second Amendment to the United States Constitution in 1951, no one has been elected as a President twice. Furthermore, no one has served more than two years of tenure.
