The president of the Senate of Chile is the presiding officer of the Senate of Chile.

The position comes after the Ministers of State in the line of succession of the President of Chile in case of temporary incapacitation or vacancy, according to Article 29 of the Constitution of Chile.

However, in the official communications the President holds the title of Excelencia ("Excellency").

The President is elected among current senators by the members themselves, and forms the Mesa de la Corporación (Committee of Chambers of the Congress) along with the Senate's Vice President.

The President's responsibilities include decreeing the summons to the Senate for its sessions, presiding over sessions and directing the debates on the Senate floor, acting as a representative of the Senate by defending its parliamentary jurisdiction and dignity, and presiding over the sessions of the Congreso Pleno (plenary meeting of both chambers).
