José Ignacio María del Corazón de Jesús de Santa Clara Francisco Javier Juan Nepomuceno Antonio de Padua Pavón Jiménez (11 August 1791 – 25 May 1866), known as José Ignacio Pavón, was a Mexican civil servant, and briefly, for two days, interim President of Mexico during the final months of a civil war, the War of Reform, being waged between conservatives and liberals, in which he served as president for the Conservatives, in opposition to President Benito Juarez, head of the Liberals.

He continued his education in the Colegio de San Ildefonso in Mexico City, where he studied philosophy and law (cánones y leyes).

After Mexico gained its independence in 1821, and political parties emerged supporting either a republic or a monarchy, Ignacio tended to keep his distance from both factions, though he leaned towards the republicans.

[1] As the First Mexican Empire fell in 1822, he rejoiced in the fall of the monarchy and took an active role in politics, hoping that the installation of a new congress could proceed quickly.

[2] In April 1823 the Supreme Executive Power assigned him a senior post within the Department of the Treasury, and also made him interim governor of the State of Tabasco.
