'''碳酸锰'''是化学式为MnCO<sub>3</sub>的无机化合物，以[[菱锰矿]]的形式存在于自然界中。2005年全球产量约为20000吨。<ref name=Reidies>Arno H. Reidies "Manganese Compounds" Ullmann's Encyclopedia of Chemical Technology 2007; John Wiley</ref>  

== 制备与用途 ==
用碱金属碳酸盐处理水溶性Mn<sup>2+</sup>盐可导致碳酸锰的沉淀。碳酸锰不溶于水，但在强酸作用下生成Mn<sup>2+</sup>盐而溶解。

碳酸锰于200&nbsp;°C时分解，生成[[二氧化碳]]和[[一氧化锰]]：
:<math>\mathrm{MnCO}_3 \longrightarrow \mathrm{MnO} + \mathrm{CO}_2</math>

此法多用于生产[[二氧化锰]]及[[干电池]]。<ref name=Reidies/>

碳酸锰常用于化肥的添加剂，用来处理锰缺乏植物。还用于保健品及陶瓷制品上釉。<ref>{{Cite web |url=http://www.stainedfloor.com/Manganese_Recipes.html |title="How To Stain Concrete with Manganese" |accessdate=2009-09-09 |archive-date=2009-09-19 |archive-url=https://web.archive.org/web/20090919024557/http://www.stainedfloor.com/Manganese_Recipes.html |dead-url=no }}</ref>

== 毒性 ==
锰元素对于[[需氧生物]]来说是必需的，且通常锰化合物毒性也并不大。[[锰中毒]]可能由长时间暴露在含锰尘土或烟雾中所导致。
