Potassium hexachloroplatinate is the inorganic compound with the formula K2PtCl6. It is a yellow solid that is an example of a comparatively insoluble potassium salt. The salt features the hexachloroplatinate(IV) dianion, which has octahedral coordination geometry.

The precipitation of this compound from solutions of hexachloroplatinic acid was formerly used for the determination of potassium by gravimetric analysis. It is also useful as an intermediate in the recovery of platinum from wastes.

Potassium hexachloroplatinate may be reduced by hydrazine dihydrochloride to give the corresponding tetrachloroplatinate salt.
