碘化锶（SrI₂），由锶和碘元素构成的盐，离子化合物，可溶于水，易潮解，在制药中可用于替代碘化钾。

碘化锶可由碳酸锶和碘化氢反应制备，相关反应方程序如下：

SrCO₃ + 2HI → SrI₂ + H₂O + CO₂

当暴露于空气中时，碘化锶会发黄。纯净的碘化锶更柔软和有韧性，而刚暴露时其表面出现粉红色或桃色。可用于导电和导热，建筑物料，和各种合金的造成部分。在高温下（有空气），碘化锶完全分解，生成氧化锶和自由的碘。

Strontium iodide (SrI₂) is a salt of strontium and iodine. It is an ionic, water-soluble, and deliquescent compound that can be used in medicine as a substitute for potassium iodide . It is also used as a scintillation gamma radiation detector, typically doped with europium, due to its optical clarity, relatively high density, high effective atomic number (Z=48), and high scintillation light yield.
