In chemistry, the perbromate ion is the anion having 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.[1] Unlike its chlorine (ClO−4) and iodine (IO−4) analogs, it is difficult to synthesize.[2] It has tetrahedral molecular geometry.[3]

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

The perbromate ion is a strong oxidizing agent.[2] The reduction potential for the BrO−
4/Br− couple is +0.68 V at pH 14. This is comparable to selenite's reduction potential.
