The present invention discloses a hydrocracking catalyst intermediate, a hydrocracking catalyst, and preparation methods of the hydrocracking catalyst intermediate and the hydrocracking catalyst. According to the present invention, the hydrocracking catalyst intermediate comprises a hydrogenation activity metal component, a carrier containing an acid cracking component, and a specific organic compound, and does not require a hydrogen sulfide generation reaction and a vulcanization reaction between hydrogen sulfide and an active metal during calcination vulcanization, such that the problem that the temperature increase is too rapid during the traditional catalyst vulcanization process can be avoided; and the hydrocracking catalyst has advantages of complete vulcanization, good metal dispersibility, and good hydrogenation property.
