Manganese(II) nitrate is an inorganic compound with formula Mn(NO₃)₂. Each formula unit is composed of one Mn²⁺cation and two NO₃⁻ anions and varying amounts of water. Most common is the tetrahydrate Mn(NO₃)₂·4H₂O, but mono- and hexahydrates are also known as well as the anhydrous compound. Some of these compounds are useful precursors to the oxides of manganese.

Manganese(II) nitrate can be prepared by dissolving manganese(II) carbonate in dilute nitric acid:

It can also be prepared from manganese dioxide and nitrogen dioxide.

On heating to 300°C, aqueous solutions of manganese(II) nitrate thermally decompose to form MnO₂ and NO₂ as products. Upon further heating, the MnO₂ loses oxygen to form Mn₂O₃ and eventually Mn₃O₄.
