The President of the Legislative Assembly is the presiding officer of the Legislative Assembly of Costa Rica. The president is elected at the first meeting of the Assembly in each legislative year by a simple majority vote of the deputies.

The powers of the office are established in Article 27 of the Regulations of the Legislative Assembly. The officeholder presides over debates, appoints standing committees, refers legislative bills to the appropriate committees, grants the floor and calls deputies to order, and signs (together with the secretaries) the minutes, laws, and other legislative provisions. The president may also grant leave of absence to deputies and oversees internal administrative and procurement processes in accordance with applicable legislation.

Costa Rica has maintained a presiding officer for its legislature since the establishment of its first Congress under the Fundamental Law of the State of Costa Rica. The current structure of the office is defined by the 1949 Constitution, which replaced the earlier Constitutional Congress with the present Legislative Assembly.
