Mangan silih tunggil datu kimia antuk simbol Mn miwah wilangan atom 25. Punika kapah katemuin dados datu bébas ring palemahan;^[3] ketah katemuin ring mineral macampuh sareng wesi. Mangan punika logam transisi makudang kawigunaan ring industri paduan, kautama ring wesi tahan karat.

Kapertama kaisolasi warsa 1774, mangan kautama kaanggén ring produksi baja. Ketah ring laboratorium marupa uyah tangi tua kalium permanganat. Punika kawéntenan situs aktip ring makudang énzim.^[4] Sané nudut manah punika pawigunaan Mn-O gugus, kompléks évolusi oksigén, ring produksi oksigén olih entik-entikan.
