Nsutite is a manganese oxide mineral with formula: (Mn4+1−xMn2+xO2-2x(OH)2x where x = 0.06–0.07).

[4] It is found in most large manganese deposits and was first discovered in Nsuta, Ghana.

Nsutite is a dull mineral with a hardness of 6.5–8.5 and an average specific gravity of 4.45.

[4] Nsutite has been used as a cathode in zinc–carbon batteries, but synthetic manganese oxide is gradually replacing it.
