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.

[2][3] Stannoidite was first described in 1969 for an occurrence in the Konjo mine, Okayama prefecture, Honshu Island, Japan.
