The LXV Legislature of the Congress of the Union (65th Congress) was a meeting of the legislative branch of Mexico, composed of the Chamber of Deputies and the Senate of the Republic. It convened on 1 September 2021, and ended on 31 August 2024, during the final three years of President Andrés Manuel López Obrador's presidency.

The Chamber of Deputies was elected in the 2021 legislative election, in which Juntos Hacemos Historia, consisting of the National Regeneration Movement (Morena), the Labor Party (PT), and the Ecologist Green Party of Mexico (PVEM), kept their majority but did not reach the two-thirds supermajority required to pass López Obrador's proposed constitutional reforms.^[1] This legislature was notable for being the first where deputies were eligible for reelection,^[2] with 129 out of the 500 seats being filled by returning deputies.^[3]
