Potassium hexacyanochromate(III) is an inorganic compound with the formula K₃[Cr(CN)₆]. It consists of three potassium cations and [Cr(CN)₆]³⁻ anion. It is a yellow, air-stable, paramagnetic solid. It is isomorphous with potassium ferricyanide.

The salt is prepared by treating chromium(III) salts with KCN.[1][2]
