Hauerite is a manganese sulfide mineral with the chemical formula Mn S₂. It forms reddish brown or black octahedral crystals and it is usually found associated with the sulfides of other transition metals such as rambergite.

It was discovered in Austria in 1846 and named after the Austrian geologists, Joseph Ritter von Hauer (1778–1863) and Franz Ritter von Hauer (1822–1899).^[1]^[2]^[3]
