An acyl halide, alternatively known as an acid halide is an organic compound consisting of the functional group RCOX, where R is a hydrocarbon chain and X is a halide, such as chlorine, bromine or iodine. They can be produced from a carboxylic acid by reacting it with a compound such as phosphorous trichloride (for chlorides) or phosphorous pentabromide (for bromides).

Acyl chlorides can be reacted with alcohol in order to produce an ester and an acid. This reaction provides a better yield than the alternative; reacting a carboxylic acid and an alcohol.
