Stannoidite is a sulfide mineral composed of five chemical elements: copper, iron, zinc, tin and sulfur. Its name originates from Latin stannum (tin) and Greek eides (or Latin oïda meaning "like"). The mineral is found in hydrothermal Cu-Sn deposits.[1][2]

Stannoidite was first described in 1969 for an occurrence in the Konjo mine, Okayama prefecture, Honshu Island, Japan.[2]
