Cuprospinel is a mineral. Cuprospinel is an inverse spinel with the chemical formula CuFe2O4, where copper substitutes some of the iron cations in the structure. Its structure is similar to that of magnetite, Fe3O4, yet with slightly different chemical and physical properties due to the presence of copper.

The type locality of cuprospinel is Baie Verte, Newfoundland, Canada, where the mineral was found in an exposed ore dump. The mineral was first characterized by Ernest Henry Nickel, a mineralogist with the Department of Energy, Mines and Resources in Australia, in 1973. Cuprospinel is also found in other places, for example, in Hubei province, China and at Tolbachik volcano in Kamchatka, Russia.
