Tribromoethylene is a bromoalkene and a trihaloethylene with the chemical formula C₂HBr₃. It can be made from 1,1,2,2-tetrabromoethane.^[3]

Tribromoethylene reacts with potassium hydroxide to yield dibromoacetylene via dehydrobromination,^[4] this reaction is analogous to the synthesis of dichloroacetylene from trichloroethylene. Tribromoethylene reacts with nitric acid to form dibromoacetic acid.^[5]
