**一碘化銦**是一種無機化合物，化學式為 InI。它可由銦和碘或三碘化銦在 300~400 °C 的真空中反應，或在 350 °C 和碘化汞反應製得：

　
: $\mathrm {2\ In+I_{2}\longrightarrow 2\ InI} $

　
: $\mathrm {2\ In+InI_{3}\longrightarrow 3\ InI} $

　
: $\mathrm {2\ In+HgI_{2}\longrightarrow 2\ InI+Hg} $

它是紅棕色反磁性固體，熔融後為黑色。它屬正交晶系 _Cmcm_ 空間群，晶胞參數 a=475 pm，b=1276 pm，c=491 pm。
