The San Carlos Fortress (in Spanish: Fortaleza de San Carlos) is an 18th-century fortress in the city of Perote, in the Mexican state of Veracruz. It is also known as the Fort of San Carlos, Perote Castle, the Castle of San Carlos, Perote Prison, San Carlos de Perote Fortress, and San Carlos de Perote Castle. In March 1843, Guadalupe Victoria, who had served as Mexico's first President in the 1820s, died in the San Carlos Fortress complex. He suffered from epilepsy and was receiving medical treatment in Perote.
