The Kapauri–Sause (Kapori–Sause) languages form a small language family spoken along the middle Taritatu River in the Jayapura Regency of Papua, Indonesia. They are two languages, Kapauri (Kapori) and Sause, which are not particularly close.

There is a history of linking at least Kapauri to the Kaure languages (see Kaure–Kapori languages). However, they show no particular affiliation, and Kapauri appears to be closer to Kwerba. Usher demonstrated a connection instead with another erstwhile isolate, Sause, together forming a branch of Kwerbic.^[1] A partial reconstruction of proto-Kapauri–Sause can be found there.
