Yah-ta-hey is a census-designated place in McKinley County, New Mexico, United States. As of the 2000 census, the CDP population was 580. The English name for this place is an approximation of a Navajo greeting, though the actual Navajo name means "just like a devil", the nickname for Anglo storekeeper J.B. Tanner. Tanner operated the trading post located here, and was criticized by the local community for his greedy business practices.
