碘化金是一种无机化合物，化学式为AuI₃，不稳定，在空气中缓慢分解为碘化亚金和碘。

碘化金可溶于碱金属碘化物溶液，形成[AuI₄]。

Gold iodide (AuI₃) is the chemical compound with the formula AuI₃. Although Au₂I₆ is predicted to be stable, gold(III) iodide remains an example of a nonexistent compound. Attempts to isolate pure samples result in the formation of gold(I) iodide and iodine:
