Jamamadi (also known as Yamamadí or Canamanti) is an Arauan language spoken by about 200 people scattered over Brazil.

The language has an Object Subject Verb word order, and is frequently cited as an example of this type. The sentence "Jose caught the piranha" would therefore come out as Piranha Jose caught.

The dialects of Jamamadi that are or were once spoken include Bom Futuro, Pauini, Mamoria and Cuchudua. Jurua and Tukurina are sometimes listed as dialects, but may be separate languages.
