一氧化锰是锰的一种氧化物，化学式MnO，在自然界中以罕见的方锰矿形式存在。
一氧化锰可由氢气还原锰的高价氧化物得到，如：
![\mathrm{MnO}_2 + \mathrm{H}_2 \longrightarrow \mathrm{MnO} + \mathrm{H}_2\mathrm{O}](/Images/godic/202501/25/175a3d41c4b9ed935f48cb51022f01841930.png")
商业上用氢气、一氧化碳或甲烷还原二氧化锰制得：
![\mathrm{MnO}_2 + \mathrm{CO} \longrightarrow \mathrm{MnO} + \mathrm{CO}_2](/Images/godic/202501/25/43f5c4f4a5c5959982cbbd2f6ac2a0f51930.png")
一氧化锰也可由碳酸锰的热分解制得：
![\mathrm{MnCO}_3 \longrightarrow \mathrm{MnO} + \mathrm{CO}_2](/Images/godic/202501/25/9acd4ed2343aaa29f77ce643a5b8698a1930.png")
一氧化锰不溶于水，是一种碱性氧化物，溶于酸形成锰(II)盐。
