Ocotlán de Venustiano Carranza

Founded on 1 March 1935, south of Tecamachalco, Ocotlán de Venustiano Carranza belongs to Yehualtepec in east-central Puebla. Ocotl is the ocote pine and tlan a place of plenty, so Ocotlán means "where ocote pines abound"; the surname honours Venustiano Carranza, the president under whose government the 1917 Constitution was enacted. It stands at about 2,080 m and had 1,828 people in 2020.

The municipality of Yehualtepec, "ringed by hills", was originally Nahua; a confraternity of the Immaculate Conception existed from 1588, in 1604 the area joined the fourth congregation, in the 19th century it belonged to the Tecamachalco district and in 1895 it became a municipality. It covers about 126 km² between 1,960 and 2,600 m and is mostly plain with rocky low hills.

The municipality sits on a watershed: half drains to the Atoyac and the Balsas, half to the Salado River and the Papaloapan; its main watercourses are irrigation channels. From above, the village sits among the valley's fields. It borders Tecamachalco, Palmar de Bravo, Tlacotepec de Benito Juárez and Xochitlán Todos Santos.
