Wyandot is the Iroquoian language traditionally spoken by the people known as Wyandot or Wyandotte, descended from the Tionontati. It is considered a sister to the Wendat language, spoken by descendants of the Huron-Wendat Confederacy. It was last spoken, before its revival, by members located primarily in Oklahoma, United States, and Quebec, Canada. Linguists have traditionally considered Wyandot as a dialect or modern form of Wendat.

The Wyandot people are Indigenous peoples of the Northeastern Woodlands of North America, and speakers of an Iroquoian language, Wyandot.
