The Federal Constitution of the United Mexican States of 1824 (Spanish: Constitución Federal de los Estados Unidos Mexicanos de 1824) was enacted on October 4 of 1824, after the overthrow of the Mexican Empire of Agustin de Iturbide. In the new constitution, the republic took the name of United Mexican States, and was defined as a representative federal republic, with Catholicism as the official and unique religion. It was replaced by the Federal Constitution of the United Mexican States of 1857.

After the abdication of Agustin de Iturbide, the Mexican Empire was dissolved and there was established a Supreme Executive Power formed by a triumvirate whose members were Generals Pedro Celestino Negrete, Nicolás Bravo and Guadalupe Victoria, whose substitutes were Jose Mariano Michelena, Vicente Guerrero and Miguel Dominguez. This Supreme Executive Power was a provisional government to called a new Constituent Congress. The new Congress was installed on 7 November 1823.

Among the members of Congress, two ideological tendencies were observed. The Centralists included Fray Servando Teresa de Mier, the priest Jose Maria Becerra Jimenez, Carlos María de Bustamante, Juan José Ignacio Espinosa de los Monteros, Rafael Mangino y Mendívil and the priest José Miguel Guridi y Alcocer. On the other hand the Federalists included Miguel Ramos Arizpe, Lorenzo de Zavala, Manuel Crescencio Rejón, Valentín Gómez Farías, Juan de Dios Cañedo, Juan Bautista Morales, Juan Cayetano Gómez de Portugal, Francisco García Salinas and Prisciliano Sánchez. Years later, these ideologies formed the Liberal Party and the Conservative Party.
