The invention provides diesel oil and a preparation method thereof. The preparation method comprises the following steps: mixing coal-liquefied hydrogenation-stabilized oil and biomass oil or biodiesel oil so as to obtain mixed oil, wherein the coal-liquefied hydrogenation-stabilized oil is full-range distillate oil obtained by hydrogenation of crude coal directly-liquefied oil, or distillate oil with a fractionating temperature smaller than 350 DEG C; respectively subjecting the mixed oil to hydrorefining reaction and hydro-upgrading reaction so as to obtain a hydrogenation product; and subjecting the hydrogenation product to fractionation at a cutting temperature larger than or equal to 165 DEG C so as to obtain the diesel oil. By mixing the coal directly-liquefied hydrogenation-stabilized oil and the biodiesel oil or the biomass oil through the processes of hydrorefining, hydro-upgrading and fractionation to prepare the diesel oil, the preparation method provided by the invention realizes mutual complementarities of advantages of two raw materials, and facilitates to improving the cetane number and the lubricity of a coal directly-liquefied diesel oil product.
