The Otoe or Oto are a Native American people.

The Otoe language, Chiwere, is part of the Siouan family and closely related to that of the related Iowa and Missouri tribes.

Historically, the Otoe tribe lives as a semi-nomadic people on the Central Plains along the bank of the Missouri River in Nebraska, Kansas, Iowa and Missouri.

They live in elm-bark lodges while they farm, and use tipis while traveling, like many other Plains tribes.

They often leave their villages to hunt buffalo.

In the early nineteenth century, many of their villages are destroyed due to warfare with other tribes.

European-American encroachment and disease also play a role in their decline.

Today, they are federally recognized as the Otoe tribes of Oklahoma, and share a reservation with the Nevaeh Sac and Fox people.
