A catalyst for hydrocracking heavy hydrocarbon oils includes a porous inorganic carrier composed mainly of alumina or titania, and two or more catalytic metal components composited with the carrier. The metals of the catalytic metal components are either (a) V and at least one element selected from Zn, Fe, Co, Ni, Cu, Ag, Sn and Pb or (b) Mo and at least one element selected from Zn, Cu, Ag, Sn, Pb and the lanthanum-series elements. The catalyst has at least 60% of its total pore volume in pores with a diameter of 200 Åor more, at least 40% of its totalpore volume in pores with a diameter of 300 Åor more and not more than 20% of its total pore volume in pores with a diameter of at least 1000 Å. Disclosed also is a process for hydrocracking a heavy hydrocarbon oil in the presence of the above catalyst.
