Jalapa Mazatec is a Mazatecan language. An estimate from 1990 suggested it was spoken by 15,000 people, one-third of whom are monolingual, in 13 villages in the vicinity of the town of San Felipe Jalapa de Díaz in the Tuxtepec District of the Mexican state of Oaxaca. A 2016 study, published in 2019, estimated the Mazatec dialects to have 220,000 speakers. Egland (1978) found 73% intelligibility with Huautla, the prestige variety of Mazatec. Literacy in Jalapa is taught alongside Spanish in local schools.
