Tepeaca is a municipality in the Mexican state of Puebla in southeastern Mexico.

The town was originally founded by Hernán Cortés as Segura de la Frontera.

In the parish of San Francisco de Asís is a Child Jesus image called the Santo Niño Doctor de los Enfemos.

The image used to belong to a nun of the Order of Josephine at Concepción Béistegui Hospital in Mexico City.

When the nun was transferred to Tepeaca, she brought the image with her and had it with her as she treated the sick.
