Trois Sauts (English: three waterfalls) or Ɨtu wasu is a cluster of four Amerindian Wayampi and Teko[4] villages on the Oyapock River in French Guiana near the border with Brazil.

Trois Sauts contains the villages of Roger, Zidock (also Zidok), Yawapa, and Pina.

The name was a mistranslation, because the waterfall has four levels making it impossible to pass by boat, and thus isolating the upstream area in Brazil from the downstream in French Guiana.

[8] Even though Trois Sault is an isolated community and far from the gold fields of Camopi, the population of the villages had the highest contamination with mercury, because they live on cassave, hunting and fishing without access to supermarkets.

[5] In 2020, a hydroelectric power plant in the waterfall was completed in order to provide electricity for the villages.
