Sulfur dibromide is the chemical compound with the formula SBr₂. It is a very toxic and vile smelling gas. Sulfur dibromide, like sulfur chlorides and disulfur dibromide, has a characteristic smell, like that of burning rubber.

Sulfur dibromide readily decomposes into S₂Br₂ and elemental bromine. In analogy to sulfur dichloride, it hydrolyzes in water to give hydrogen bromide, sulfur dioxide and elemental sulfur.

SBr₂ can be prepared by reacting SCl₂ with HBr. It can also be made by reacting sulfur with Br2, but due to its rapid decomposition it cannot be isolated at standard conditions. Instead, the more stable S₂Br₂ is obtained.^[1]
