**三溴化鈽**是一種無機化合物，化學式為 PuBr3，存在無水物和水合物。無水物和水合物在放置時會因為鈽的 α 輻射而分解。

## 製備及性質

三溴化鈽可由二氧化鈽和溴化氫或和一氧化碳和溴在 650~800 °C 反應得到；也可由鈽的草酸鹽（Pu2(C2O4)3·9H2O 或 Pu (C2O4)2·6H2O）在 500 °C 和溴化氫反應得到。

　
: ${\ce {2 PuO2 . x H2O + 8 HBr -> 2 PuBr3 + (4 + 2 x) H2O + Br2}}$

　
: ${\ce {Pu2(C2O4)3 . 10 H2O + 6 HBr -> 2 PuBr3 + 3 CO + 3 CO2 + 13 H2O}}$

三溴化鈽六水合物可從溶液中結晶得到。

它和三氧化二銻在真空中加熱反應，可以得到 PuOBr。它和 K2COT 在 THF 中於−10~−20 °C 反應，可以得到 KPu (COT)2·2THF。
