Benzotriazole (BTA) is a heterocyclic compound with the chemical formula . It can be viewed as the fusion of a benzene and triazole rings. It is a white solid, although impure samples can appear tan. It is used as a corrosion inhibitor for copper and silver.

==Structure and synthesis== Benzotriazole features two fused rings. It can in principle exist as tautomers, but X-ray crystallography establishes the structure with hydrogen at the 1 position. The N=N and HN-N distances are 1.306 and 1.340 Å.
