Oro Win is a moribund Chapacuran language spoken along the upper stretches of the Pacaás Novos River in Brazil.

Oro Win is one of only five languages known to make use of a voiceless bilabially post-trilled dental stop, [t͡ʙ̥].

As of 2010, there were only six known speakers of Oro Win in Brazil, and all of them were over 50 years of age.[3]
