Kosmochlor is a rare chromium sodium clinopyroxene with the chemical formula NaCr3+Si2O6.

The name is from German kosmisch, for its occurrence in meteorites, and the Greek chlor, for green.[4] It was first reported in 1897 from the Toluca meteorite, Jiquipilco, Mexico.[2]

It occurs as a major constituent of some jadeitites and as an accessory mineral of some iron meteorites. Associated minerals include cliftonite (graphite), chromian diopside, troilite at Toluca; daubreelite, krinovite, roedderite, high albite, richterite, chromite (Canyon Diablo); and jadeite, chromite and chlorite (Burma).[3]
