Bismuth iodate is an inorganic compound with the chemical formula Bi(IO₃)₃. Its anhydrate can be obtained by reacting bismuth nitrate and iodic acid, dissolving the resulting precipitate in 7.8 mol/L nitric acid, and heating to volatilize and crystallize at 70 °C; The dihydrate can be obtained by reacting bismuth nitrate and potassium iodate or sodium iodate. It is obtained by evaporation and crystallization in 7 mol/L nitric acid at 50 °C. Its basic salt BiOIO₃ is known.
