Cabriite, formula- (Pd2SnCu) is a mineral first found in the eastern Siberian region of Russia and named for the Canadian mineralogist Louis J. Cabri (born 1934). It was named after Dr. Louis J. Cabri, a Canadian mineralogist working at the Canadian Centre for Mineral and Energy Technology, Ottawa, Canada. He is recognized for his contribution in providing detailed descriptions of many platinum group minerals.

Cabriite occurs in the huge mooihoekite ore, and also in the galena–chalcopyrite veins. It is often associated with minerals such as mooihoekite, putoranite, talnakhite, paolovite, sobolevskite, sperrylite, gravesite, polarite, auricupride, cassiterite, stannite, chalcopyrite, valleriite, Galena, froodite, magnetite, silver, and sphalerite.
