Copper(I) cyanide is an inorganic compound with the formula CuCN. This off-white solid occurs in two polymorphs; impure samples can be green due to the presence of Cu(II) impurities. The compound is useful as a catalyst, in electroplating copper, and as a reagentin the preparation of nitriles.

Copper cyanide is insoluble in water but rapidly dissolves in solutions containing CN to form [Cu(CN)3]2− and [Cu(CN)4]3−, which exhibit trigonal planar and tetrahedral coordination geometry, respectively. These complexes contrast with those of silver and gold cyanides, which form [M(CN)2] ions in solution. The coordination polymer KCu(CN)2 contains [Cu(CN)2] units, which link together forming helical anionic chains.

Copper cyanide is also soluble in concentrated aqueous ammonia, pyridine and N-methylpyrrolidone.

Cuprous cyanide is used for electroplating copper.
