Barium bromite, Ba(BrO₂)₂, is formally the barium salt of bromous acid. It was the first bromite to be isolated, as the monohydrate, which is formed by the controlled disproportionation of barium hypobromite at pH 11–12 and 0 °C. The anhydrous salt can be prepared by heating barium bromate to 250 °C in vacuo.

2 Ba(BrO₃)₂ → 2 Ba(BrO₂)₂ + O₂
