The LXIII Legislature of the Congress of the Union, the 63rd session of the Congress of Mexico, was 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 2015 election, only held office in the current legislature.
