'''Bukovite''' is a rare selenide mineral with formula Tl<sub>2</sub>Cu<sub>3</sub>FeSe<sub>4</sub>. It is a brown to black metallic mineral which crystallizes in the tetragonal system.<ref name=Handbook/>
It was first described in 1971 for an occurrence in the Bukov uranium mine, Rožná deposit, Vysočina Region, Moravia, Czech Republic.<ref name=Mindat/> It has also been reported in Skrikerum, near Tryserum, Kalmar, Sweden; near Vernet-la-Varenne, Puy-de-Dôme, France; and Tuminico, Sierra de Cacho, La Rioja Province, Argentina.<ref name=Handbook/>
