磷化锌是一种无机化合物，化学式为Zn₃P₂。

由红磷与锌粉混合后经高温烧成反应，然后冷却、粉碎得到磷化锌成品。

Zinc phosphide (Zn₃P₂) is an inorganic chemical compound. It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide. Zn₃P₂ is a semiconductor with a direct band gap of 1.5 eV. and may have applications in photovoltaic cells. A second zinc phosphide is known, with the stoichiometry ZnP₂.
