Tolatecan is a proposal by Campbell and Oltrogge (1980) linking two language families of Mesoamerica, Tequistlatecan (Chontal of Oaxaca) and Tol/Jicaque languages of Honduras. Later, Campbell (1997) said that Tolatecan is not likely to be a valid language family.
Both Tequistlatecan and Tol have been at times also included in the larger Hokan proposal, but without any especial relationship within it.
Below is a comparison of selected basic vocabulary items in Proto-Jicaque and the Tequistlatecan languages.
