1,2-Dibromobenzene (o-dibromobenzene) is an aryl bromide and isomer of dibromobenzene.

It is one of three isomers, the others being 1,3- and 1,4-dibromobenzene.

It is a colorless liquid, although impure samples appear yellowish.

The compound is a precursor to many 1,2-disubstituted derivatives of benzene.

For example, it is a precursor to 1,2-dicyanobenzene[1] and dithioethers.
