Provisional president of the Argentine Senate

The provisional president of the Senate of the Argentine Nation (), commonly known as the provisional president, is the highest-ranking official in the Upper House, except in the presence of the incumbent president of the Senate, a position held by the vice president of Argentina.

The provisional president is second in line to the presidency of Argentina. The position is filled through a vote by fellow senators at the start of each legislative year, typically held within the first ten days of December. Additionally, the chamber's minority parties are responsible for selecting three vice presidents.
