Nickel(II) fluoride is the chemical compound with the formula NiF₂. It is an ionic compound of nickel and fluorine and forms yellowish to green tetragonal crystals. Unlike many fluorides, NiF₂ is stable in air.

Nickel(II) fluoride is also produced when nickel metal is exposed to fluorine. In fact, NiF₂ comprises the passivating surface that forms on nickel alloys (e.g. monel) in the presence of hydrogen fluoride or elemental fluorine. For this reason, nickel and its alloys are suitable materials for storage and transport these fluorine and related fluorinating agents. NiF₂ is also used as a catalyst for the synthesis of chlorine pentafluoride.
