'''溴酸铷'''是[[铷]]的[[溴酸盐]]，化学式 RbBrO<sub>3</sub>。

== 制备==
溴酸铷可以由[[碳酸铷]]和溴酸反应而成：<ref name="Buell">Harold D. Buell, C. R. McCrosky: "The preparation and study of the rarer alkali bromates. Rubidium bromate." in ''J. Am. Chem. Soc'' '''1921''', ''43''(9), S. 2031–2034. {{doi|10.1021/ja01442a006}}</ref>

:<math>\mathrm{Rb_2CO_3 + 2\ HBrO_3 \longrightarrow  2\ RbBrO_3 + H_2O + CO_2 \uparrow}</math>

它也可以由碳酸铷和[[溴酸钠]]反应而成。<ref name="Stenger">Vernon A. Stenger, Richard M. Van Effen: "Solubilities of Alkali Metal Bromates and Iodates in Methanol at Room Temperature" in ''J. Chem. Eng. Data'' '''1999''', ''44''(2), S. 173–174. {{doi|10.1021/je980120a}}</ref>
