Mangan(III) oksid je hemijsko jedinjenje, koje ima molekulsku masu od 157,874 Da.

Mangan(III) oksid ima izražena slabo bazna svojstva. Rastvaranjem u kiselinama bi trebalo da nastane Mn³⁺ jon. Međutim, ovaj jon je jako oksidaciono sredstvo koje može oksidovati prisutni anjon, pri čemu se sam redukuje do mangana(II). Ukoliko se anjon kiseline ne može oksidovati, u vodenim rastvorima dolazi do disproporcionisanja mangan(III) jona:

\mathrm {2Mn^{3+}+2H_{2}O\longrightarrow \;MnO_{2}+Mn^{2+}+4H^{+}}
