Dibromochloromethane is a compound with formula CHBr₂Cl. It is a trihalomethane.

Dibromochloromethane was formerly used as a flame retardant and as an intermediate in chemicals manufacturing. Today it is used only as a laboratory reagent.

Dibromochloromethane is also a disinfection byproduct, formed by the reaction of chlorine with natural organic matter and bromide ions in the raw water supply. As a result, it is commonly found in chlorinated drinking water.

Small quantities of dibromochloromethane are produced in ocean by algae.
