An object of the present invention is to provide a method for producing 5-hydroxymethyl-2-furfural (5-HMF) with suppressed production of byproducts. The present invention provides a method for producing 5-HMF, comprising the step of performing a dehydration reaction of a carbohydrate comprising a hexose as a constituent sugar or a derivative thereof to produce 5-hydroxymethyl-2-furfural, wherein the dehydration reaction is performed in the presence of activated carbon. The present invention also provides a method for producing a carbohydrate composition comprising 5-hydroxymethyl-2-furfural, comprising the step of heating a carbohydrate composition comprising one or more selected from the group consisting of a carbohydrate comprising a hexose as a constituent sugar and a derivative thereof, in the presence of an acid catalyst and activated carbon at a temperature of 90 to 400° C.
