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.

The Mexican War of Independence (1810–1821) severed control that Spain had exercised on its North American territories, and the new country of Mexico was formed from much of the individual territory that had comprised New Spain. The victorious rebels issued a provisional constitution, the Plan de Iguala. This plan reaffirmed many of the ideals of the Spanish Constitution of 1812 and granted equal citizenship rights to all races. In the early days of the country, there was much disagreement over whether Mexico should be a federal republic or a constitutional monarchy. One of the leaders of the revolution became the first monarch, Agustin I.

Discontent with Agustin's national government grew, Brigadier Antonio López de Santa Anna initiated an insurrection. Generals issued the Plan of Casa Mata on 1 February 1823. The plan won the support of the provinces because it included a provision granting local authority to the provincial deputations. The election of a new legislature constituted the plan’s principal demand, because provincial leaders considered the composition of the first congress to be flawed. Following the precedent of the Hispanic Cortes, Mexican political leaders considered the executive to be subservient to the legislature. Thus, a new congress, which did not possess the liabilities of the old, could restore confidence even if the executive remained in place. Mexican politicians, of course, expected the new body to keep the emperor in check. Agustin abdicated in March 1823.
