Zusammenfassung:	PROBLEM TO BE SOLVED: To produce a low-sulfur diesel light oil, excellent in hue and stability thereof by bringing a petroleum distillation distillate oil having a specific sulfur content and a specified boiling point into contact with hydrogen under specific conditions. SOLUTION: This method for producing a low-sulfur diesel light oil comprises a first step for bringing a petroleum distillation distillate oil having 0.1-2.0wt.% sulfur content and 150-400 deg.C boiling point which is a raw material oil into contact with hydrogen in the presence of a hydrogenating catalyst under conditions of 330-450 deg.C temperature and 45-100kg/cm pressure and providing a product oil having =-10 hue expressed in terms of a value of Saybolt color and a second step for bringing the resultant product oil into contact with hydrogen in the presence of a hydrogenating catalyst under conditions of 200-320 deg.C temperature and 45-100kg/cm pressure and affording a product oil having a hue exceeding that expressed in terms of the value of the Saybolt color in the first step. Furthermore, the hydrogenating catalyst is obtained by supporting one or metals of Cr, Mo and W and one or more metals of Co and Ni on a porous inorganic oxide carrier such as alumina or silica-alumina.
