The LXVI Legislature of the Congress of the Union (66th Congress) is the current session of the legislative branch of Mexico, composed of the Chamber of Deputies and the Senate of the Republic. It convened on 1 September 2024, and will end on 31 August 2027,[1] covering the final month of Andrés Manuel López Obrador's term in office and the first three years of Claudia Sheinbaum's presidency.

Both chambers of Congress were elected in the 2024 general election. There were three competing forces: the Sigamos Haciendo Historia coalition, consisting of the National Regeneration Movement (Morena), the Labor Party (PT), and the Ecologist Green Party of Mexico (PVEM); the Fuerza y Corazón por México coalition, comprising the National Action Party (PAN), the Institutional Revolutionary Party (PRI), and the Party of the Democratic Revolution (PRD); and the Citizens' Movement (MC), the only party to run without allies.

Sigamos Haciendo Historia won a supermajority in the Chamber of Deputies. The coalition fell three seats short of a supermajority in the Senate, but defections by the two senators elected for the PRD on 28 August closed the shortfall to one.[2]
