Bromocyclopropane is a organobromine compound with the chemical formula C3H5Br.

[2] It is a member of haloalkane family.

The compound can be obtained by treating silver cyclopropanecarboxylate with bromine:[3] Reaction with magnesium, using diethyl ether as solvent, only gives about 25–30% of the cyclopropylmagnesium bromide Grignard reagent, with nearly as much cyclopropane formed by alternate reactions on the metal surface.

[4] The compound isomerizes on heating to produce 1-bromopropene and 3-bromopropene.

It is soluble in chloroform and methanol.
