Titanowodginite is a mineral with the chemical formula MnTiTa2O8. Titanowodginite has a Mohs hardness of 5.5 and a vitreous luster. It is an iridescent dark brown to black crystal that commonly forms in a matrix of smoky quartz or white beryl in a complex zoned pegmatite.[2][3][4]

It was first described in 1992 for an occurrence in the Tanco Mine located in southern Manitoba, Canada. It was named because it is a titanium bearing member of the wodginite group.[2][4]
