The invention discloses a hydrodewaxing method for diesel fraction. The method is as follows: a raw material of wax-containing diesel oil sequentially passes through alternatively cascaded hydrodewaxing catalyst beds and hydrofining catalyst beds, and a finally obtained hydrofining product is subjected to separation so as to obtain a product of diesel oil. The method enables average reaction temperature of the hydrodewaxing catalyst beds to be increased, thereby improving the utilization rate of a hydrodewaxing catalyst, prolonging the on-stream period of an apparatus and enhancing yield of the target product.
