What Is the Presiding Officer of the Senate Called?


The presiding officer of the United States Senate is simply called the presiding officer. The presiding officer of the Senate is also the president of the Senate and the vice president of the U.S.

If the vice president is unavailable, then the president pro tempore of the Senate, who is usually the most senior member of the majority party, presides in his or her stead or may designate another member of the majority party to do so.

Article 1, Section 3, Clause 4 of the U.S. Constitution mandates that the vice president shall preside over the Senate, but have no vote unless there is a tie.
