Abstract: A method for producing xylene, including a conversion reaction step of bringing a raw material containing a light hydrocarbon having 2 to 7 carbon atoms as a main component into contact with a crystalline aluminosilicate-containing catalyst to produce a product containing a monocyclic aromatic hydrocarbon having 6 to 8 carbon atoms and a xylene conversion step of subjecting the product to a disproportionation reaction or a transalkylation reaction.
