'''硝酸マンガン(II)'''（しょうさんマンガン、{{Lang-en-short|Manganese(II) nitrate}}）は、[[マンガン]]の[[硝酸塩]]で、化学式Mn(NO<sub>3</sub>)<sub>2</sub>で表される[[無機化合物]]。[[マンガンイオン]]Mn<sup>2+</sup>一つと[[硝酸イオン]]NO<sub>3</sub><sup>-</sup>二つで構成される。様々な[[水和物]]の形をとり、一般には四水和物や六水和物、[[無水物]]が知られる。四水和物は単斜晶系、六水和物は斜方晶系の[[結晶構造]]をとる、-30℃から25.8℃の間は六水和物、25.8℃を越えると三水和物となり、129.4℃で分解する<ref name="suzuki250"/>。[[セラミックス]]や[[触媒]]、高純度[[酸化マンガン]]の製造に用いられる<ref name="suzuki250">{{Cite book|和書

== 製法 ==
[[炭酸マンガン(II)]]を[[硝酸]]に溶解することにより得られる。
: <chem>MnCO3\ + 2HNO3 -> Mn(NO3)2\ + H2O\ + CO2</chem>
また、[[二酸化マンガン]]と[[二酸化窒素]]の反応により製造することもできる<ref name=Ullmann>Arno H. Reidies, “Manganese Compounds” in ''Ullmann's Encyclopedia of Industrial Chemistry'', 2002, Wiley-VCH, Weinheim. {{DOI|10.1002/14356007.a16_123}}</ref>。
