The President of Mexico is the person who controls the executive power in the country. Under the current constitution, this responsibility lies with the President of the United Mexican States, who is head of the supreme executive power of the Mexican Union.^[1] Throughout its history, Mexico has had several forms of government. Under the federal constitutions, the title of President was the same as the current one. Under the Seven Laws (centralist), the chief executive was named President of the Republic. In addition, there have been two periods of monarchical rule, during which the executive was controlled by the Emperor of Mexico.

The chronology of the heads of state of Mexico is complicated due to the country's political instability during most of the nineteenth century and early decades of the twentieth century. With few exceptions, most of the Mexican presidents elected during this period did not complete their terms. Until the presidency of Lázaro Cárdenas, each president remained in office an average of fifteen months.^[2]

This list also includes the self-appointed presidents during civil wars and the collegiate bodies that performed the Mexican Executive duties during periods of transition.

The Provisional Government of 1823–1824 was an organization that served as the Executive in the government of Mexico after the abdication of Agustín I, monarch of Mexican Empire in 1823.^[4] The provisional government was responsible for convening the body that created the Federal Republic and existed from 1 April 1823 to 10 October 1824.^[5]

The president and vice president did not run jointly and could be from different parties.

President-elect Obregón was assassinated before he was inaugurated for a six-year presidential term. Calles brought together revolutionaries to found a political party. Calles could not succeed himself as president, but he remained the power behind the presidency as the jefe máximo (maximum chief).
