Manganese(II) acetate is the chemical compound with the formula Mn(CH₃COO)₂. It is used as a desiccant, a catalyst, and as fertilizer.

Manganese(II) acetate can be formed by reacting acetic acid with either manganese(II,III) oxide or manganese(II) carbonate:

If manganese(II,III) oxide is used, manganese(III) oxide is produced as a byproduct.

If the anhydrous form needs to be produced, manganese(II) nitrate can be reacted with acetic anhydride.
