二硫化锡是一种无机化合物，俗称“金粉”，常用作金色的涂料。

二硫化锡可由锡和硫在碘的存在下直接化合得到，反应需要加热：

Sn + 2 S —→ SnS₂

另一种方法则是将硫化氢通入锡(IV)盐或锡(IV)酸盐溶液，沉淀得到。

Tin(IV) sulfide is a compound with the formula SnS
2. The compound crystallizes in the cadmium iodide motif, with the Sn(IV) situated in "octahedral holes' defined by six sulfide centers. It occurs naturally as the rare mineral berndtite. It is useful as semiconductor material with band gap 2.2 eV.
