PROBLEM TO BE SOLVED: To provide a method for producing an alicyclic diol, without requiring isolation of an intermediate product. SOLUTION: This method for producing the alicyclic diol expressed by formula (IV) (n is 0 or 1) comprises (1) subjecting a compound expressed by general formula: R<SP>1</SP>OOCCH=CHCOOR<SP>2</SP>(R<SP>1</SP>and R<SP>2</SP>are each a 1-10C alkyl) or the like and cyclopentadiene or dicyclopentadiene to Diels-Alder reaction in a solvent or without using the solvent, so as to form a compound which is expressed by formula (III) (n is 0 or 1) and corresponds to such a compound that an upper CH<SB>2</SB>OH group in formula (IV) is changed into COOR<SP>1</SP>and a lower CH<SB>2</SB>OH group therein is changed into COOR<SP>2</SP>, (2) adjusting an acid value of the obtained reaction mixture liquid to be not more than 8 KOHmg based on 1 g of the formed compound (III) or not adjusting the acid value when the acid value of the reaction mixture liquid is in a range specified in the above, and (3) reacting the compound (III) with hydrogen in the presence of a hydrogenation catalyst, without isolating the compound (III) from the reaction mixture liquid.
