硫酰氯是硫酸的两个-OH基团被氯替代后形成的化合物，分子式为SO2Cl2，为无色有强烈刺鼻气味的液体，在潮湿空气中发烟。它用作有机化学中的氯化试剂，可以将烷烃、烯烃、炔烃及芳香化合物的C-H键转化为C-Cl键，将醇转化为氯代烃。反应由***引发，是自由基机理，称为氯磺化反应。硫酰氯也用于药物和染料的制取。
硫的另一个常见卤氧化物为亚硫酰氯，也称氯化亚砜，分子式为SOCl2。

Sulfuryl chloride is an inorganic compound with the formula SO2Cl2. At room temperature, it is a colorless liquid with a pungent odor. Sulfuryl chloride is not found in nature, as can be inferred from its rapid hydrolysis.
Sulfuryl chloride is commonly confused with thionyl chloride, SOCl2. The properties of these two sulfur oxychlorides are quite different: sulfuryl chloride is a source of chlorine whereas thionyl chloride is a source of chloride ions. An alternative IUPAC name is sulfuroyl dichloride.
