LXIII Legislature of the Mexican Congress

The LXIII Legislature of the Mexican Congress is made up of senators and deputies that are members of their respective chambers. It convened on September 1, 2015, and concluded on August 31, 2018. It was succeeded by the LXIV Legislature in 2018.

Senators were elected to office in the 2012 election for a period of six years and therefore exercised their position also in the previous legislature; the deputies, elected in the electoral process of 2015, will hold office only in the current legislature.
