Calcium bromate, Ca(BrO₃)₂, is a calcium salt of bromic acid. It is most commonly encountered as the monohydrate, Ca(BrO₃)₂•H₂O.^{[citation needed]}

It can be prepared by reacting calcium hydroxide with sodium bromate or calcium sulfate with barium bromate. Above 180 °C, calcium bromate decomposes to form calcium bromide and oxygen.^{[citation needed]} In theory, electrolysis of calcium bromide solution will also yield calcium bromate.

It is used as a bread dough and flour "improver" or conditioner (E number E924b) in some countries.^[3]
