PROBLEM TO BE SOLVED: To industrially, advantageously and simply produce 1,9-nonanedial and/or 2-methyl-1,8-octanedial. SOLUTION: A method for producing the 1,9-nonanedial and/or 2-methyl-1,8-octanedial is carried out as follows. A 9-alkoxy-7-nonenal and/or an 8-alkoxy-2-methyl-6-octenal are isomerized in the presence of an isomerization catalyst composed of a cobalt hydride complex and the resultant isomerization products are then hydrolyzed.
