Constantino Reyes-Valerio (January 10, 1922, Zinacatepec, Puebla - December 13, 2006, Mexico City)[1] was a prominent Mexican scholar of pre-Columbian Mesoamerican cultures, particularly the Aztec and the Maya as well as the Colonial Art.

In 1947 he arrived in Mexico City, where five years later he obtained a Master's degree in Bacteriological Chemistry and Parasitology at the National Polytechnic Institute[1].

Reyes-Valerio identified the artistic contribution of Native Mexican Indians in the Colonial painting and sculpture; he coined the term Indochristian art.

He corresponded extensively with major scholars in Mexico and abroad such as George Kubler, Santiago Sebastian and Enrique Marco Dorta among others.
