Cajamarca Quechua is a variety of Quechua spoken in the districts of Chetilla, Baños del Inca and Cajamarca (Porcón) in the Peruvian province of Cajamarca. It was never spoken throughout the region, where other indigenous languages were spoken as well, e.g. Culle. Cajamarca Quechua is severely endangered, as hardly any children are now learning it. Cajamarca Quechua belongs to Quechua II, subgroup Cajamarca–Cañaris (Quechua II a, Yunkay) and is closest to Lambayeque Quechua, with which it has 94% lexical similarity. Félix Quesada published the first grammar and dictionary in 1976.
