In chemistry, the perbromate ion is the anion with the chemical formula BrO−4. It is an oxyanion of bromine, the conjugate base of perbromic acid, in which bromine has the oxidation state +7. Unlike its chlorine (ClO−4) and iodine (IO−4) analogs, it is difficult to synthesize. It has tetrahedral molecular geometry.

The term perbromate also refers to a compound that contains the BrO−4 anion or the −OBrO₃ functional group.

The perbromate ion is a strong oxidizing agent. The reduction potential for the BrO−4/Br⁻ couple is +0.68 V at pH 14. This is comparable to selenite's reduction potential.
