叠氮化溴是一种无机化合物，有爆炸性，化学式为BrN₃。

叠氮化溴由叠氮化钠和溴的反应制得：

NaN₃ + Br₂ → BrN₃ + NaBr

Bromine azide is an explosive inorganic compound with the formula BrN₃. It has been described as a crystal or a red liquid at room temperature. It is extremely sensitive to small variations in temperature and pressure, thus extreme caution must be observed when working with this reagent. This property of bromine azide has led to difficulty in discerning its crystal structure, with explosions occurring at Δp ≥ 0.05 Torr and also upon crystallization. Despite this, a crystal structure of bromine azide has been obtained using a miniature zone-melting procedure with focused infrared laser radiation. In contrast to IN₃, which forms an endless chain-like structure upon crystallization, BrN₃ forms a helical structure.
