The Iroquoian languages are a First Nation and Native American language family. They are known for their general lack of labial consonants.
Family division 
- Southern Iroquoian
- Northern Iroquoian
- Lakes Iroquoian
- Five Nations and Susquehannock
- Susquehannock (extinct)
- Wyandot (Huron–Petun) (extinct)
- Wenrohronon (extinct)
- Neutral (extinct)
- Erie (extinct)
- Tuscarora (seriously endangered)
- Nottoway (extinct)
- Laurentian (extinct)
Scholars are finding that what has been called the Laurentian language appears to be more than one dialect or language.
In 1649 the tribes constituting the Huron and Petun confederations were displaced by war parties from Five Nations villages (Mithun 1985). Many of the survivors went on to form the Wyandot tribe. Ethnographic and linguistic field work with the Wyandot (Barbeau 1960) yielded enough documentation to be able to make some characterizations of the Huron and Petun languages.
The languages of the tribes that constituted the Wenrohronon, Neutral and the Erie confederations were very poorly documented. These groups were called Atiwandaronk meaning 'they who understand the language' by the Huron, and thus are historically grouped with them.
The group known as the Meherrin were neighbors to the Tuscarora and the Nottoway (Binford 1967) and may have spoken an Iroquoian language. There is not enough data to determine this with certainty.
External relations 
Attempts to link the Iroquoian, Siouan, and Caddoan languages in a Macro-Siouan family are suggestive but remain unproven (Mithun 1999:305).
Iroquois linguistics and language revitalization 
As of 2012, a program in Iroquois linguistics, the Certificate in Iroquois Linguistics for Language Learners, offered at the Syracuse University, is designed for students and language teachers working in language revitalization.
Six Nations Polytechnic in Ohsweken, Ontario offers Ogwehoweh language Diploma and Degree Programs in Mohawk or Cayuga.
