The Kapauri–Sause (Kapori–Sause) languages form a small language family spoken along the middle Taritatu River in the Jayapura Regency of Papua, Indonesia.

Usher demonstrated a connection instead with another erstwhile isolate, Sause, together forming a branch of Kwerbic.
Usher (2020) reconstructs the consonant inventory as follows.
