The Diocese of Papantla (Latin: Dioecesis Papantlensis) is a Latin Church ecclesiastical territory or diocese of the Catholic Church in Mexico. It was erected 24 November 1922 and based in the Mexican city of Papantla, Veracruz. The diocese is a suffragan in the ecclesiastical province of the metropolitan Archdiocese of Xalapa. Along with the Dioceses of Huejutla, Tulancingo and Tampico, it lost territory in 1962 to form the Diocese of Tuxpan.
In 1901, the see was changed to Teziutlán, in Eastern Puebla, near to the border with Veracruz.
