Iroquoian languages

The Iroquoian languages (, ), occasionally referred to as the Ogwehoweh languages, are a family of indigenous languages of North America. They are known for their general lack of labial consonants. The Iroquoian languages are polysynthetic and head-marking.

As of 2020, almost all surviving Iroquoian languages are severely or critically endangered, with some languages having only a few elderly speakers remaining. The two languages with the most speakers, Mohawk (Kanienʼkéha) in New York and Canada, and Cherokee in Oklahoma and North Carolina, are spoken by fewer than 10% of the populations of their nations.
