氯化锡（II），化学式SnCl₂，为白色固体。

将锡溶于浓盐酸中，再将溶液蒸发，制得无色针状结晶SnCl₂‧2H₂O。反应式：

Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula SnCl₂. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot. SnCl₂ is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating. Tin(II) chloride should not be confused with the other chloride of tin; tin(IV) chloride or stannic chloride (SnCl₄).
