Agustín de Vetancurt (also written Vetancourt, Betancourt, Betancur; 1620–1700) was a Mexican Catholic historian and scholar of the Nahuatl language.
Born in Mexico City, Vetancurt became a Franciscan in Puebla, where he spent 40 years amongst the indigenous.
He was official chronicler of the Order, so much of his most important work Teatro Mexicano deals with matters of interest to its members.
He was helped in his work by Don Carlos de Siguenza y Gongora, and it is possible that some information on prehispanic indigenous culture came from him.
