The Northern Loloish languages, also known as Northern Ngwi, are a branch of the Loloish languages that includes the literary standard of the Yi people. In Lama's classification, it is called Nisoid, which forms the Nisoish branch together with the Axi-Puoid languages.
Another officially recognized Yi language, Southern Yi, may or may not be a Northern Loloish language, as Pelkey classifies it as a Southeastern Loloish language based on phonological innovations shared with Southeastern instead of Northern Loloish languages. Other Northern Loloish languages are listed below.
Nisu is classified as Southeastern Loloish by Pelkey, but is traditionally classified as a Northern Loloish language. Bradley also lists the endangered Kathu and Mo'ang languages of Wenshan Prefecture, Yunnan, China as Northern Loloish languages, but they were later classified as Mondzish by Lama and Hsiu.
