Chiriba (Chiriva) is a poorly attested language of Moxos Province, Bolivia which may have belonged to the Panoan family.
All that was recorded of it was a list of seven words; several of these resemble Panoan languages, especially Pakawara, and none resemble other language families.
Unattested Chumana is reported to have been related.
