PROBLEM TO BE SOLVED: To provide a hydrogenation refining process which enables a high level of desulfurization and denitrification by the same purifier as the conventional one and a process for the hydrogenation refining of a gas oil cut which can secure the flexibility of a purifier by the relaxation of its operational restrictions. SOLUTION: In the process for the hydrogenation refining of a gas oil cut by bringing the gas oil cut and hydrogen into contact with a hydrogenation refining catalyst to turn the sulfur content into not more than 150 ppm, the liquid hourly space velocity at the time of hydrogenation refining is set at 0.1-2.0 hr-1; the hydrogen to oil ratio is set at 200-500 L/L; the hydrogen pressure is set at 40-100 kg/cm2; and, at the same time, the value of dividing the hydrogen to oil ratio by the liquid hourly space velocity is set at not less than 100 hr.
