Nitrosyl bromide is the chemical compound with the chemical formula NOBr. It is a red gas with a condensation point just below room temperature. It reacts with water.

Nitrosyl bromide can be formed by the reversible reaction of nitric oxide with bromine. This reaction is of interest as it is one of very few third-order homogeneous gas reactions. NOBr is prone to photodissociation at standard pressure and temperature.

2 NO + Br₂ ⇌ 2 NOBr

Another way to make it is by way of nitrogen dioxide reacting with potassium bromide.

2NO₂ + KBr → BrNO + KNO₃
