One must be at least 30 years old to be elected to the United States Senate.

Constitutional rule

  • The U.S. Constitution sets a minimum age of 30 for senators, found in Article I, Section 3, Clause 3.
  • The same clause also requires at least nine years of U.S. citizenship and that the person be an inhabitant of the state they represent at the time of election.

Why the age is 30

  • The framers chose 30 so senators would be somewhat older and more experienced than members of the House, which has a minimum age of 25.
  • They argued that the Senate’s role required greater stability of character and breadth of information than the more directly populist House.

TL;DR: To be elected to the United States Senate, a person must be at least 30 years old, a U.S. citizen for at least nine years, and a resident of the state they will represent.
