José Chacón Medina Salazar y Villaseñor (1668 - ??) was a Spanish official who served as Governor of New Mexico between 1707 and 1712. Salazar y Villaseñor was Marquis de Peñuela and Knight of the Order of Santiago.
Jose Chacón Medina Salazar y Villaseñor was born in 1668. He joined the Spanish Army in his youth, eventually becoming an Admiral of the Marines.
He was appointed Captain General and Governor of Santa Fe de Nuevo México in 1707, in place of Francisco Cuervo y Valdés.
Chacon rebuilt the chapel at San Miguel, Santa Fe, which had been destroyed in the Pueblo Revolt uprising of 1680. Under his orders, Hurtado made a military campaign against the Navajo people.
In 1703, Sebastian Martin obtained a concession area of the land of his brother, northeast of the Pueblo of San Juan, but lost the testimony and writing documenting the lease. So in 1712, Martin asked Governor Salazar y Villaseñor for confirmation of his title. The May 23, 1712, Chacon investigated the application and decided that Martin should be protected. So, Chacón accepted the concession, voiding all other instruments and ordered Provincial Secretary Cristóbal de Góngora to grant the limits that had been requested and handed back the legal possession of it to its owner.
In 1712, Salazar y Villaseñor was replaced by Juan Ignacio Flores Mogollon in the New Mexico government .
