Boron tribromide, BBr₃, is a liquid compound containing boron and bromine. It is usually made by heating boron oxide with carbon in the presence of bromine: this generates free boron which reacts vigourously with the bromine. It is very volatile and fumes in air because it reacts vigorously with water to form boric acid and hydrogen bromide.

This compound is commercially available and acts as a strong Lewis acid, though less so than boron trifluoride and boron trichloride. Boron tribromide is commonly used in the removal of methyl ethers.
