An olefin polymerization catalyst which is a solid catalyst comprising: a fine particle carrie; (A) a transition metal compound of Group IVB metal of the periodic table, containing a ligand having a cyclopentadienyl skeleton; (B) an organoaluminum oxy- compound; and (C) an organoaluminum compound, if necessary; said transition metal compound (A) and said organoaluminum oxy-compound (B) and said.organoaluminum compound being supported on the fine particle carrier; and said solid catalyst having a bulk density of not less than 0.4 g/cm3 and a fluidity index of not less than 45 and an olefin polymerization process using the olefin polymerization catalyst. An olefin polymerization catalyst which is a prepolymerized catalyst comprising: a fine particle carrier; (A) a transition metal compound of. Group IVB metal of the periodic table, containing a ligand having a cyclopentadienyl skeleton; (B) an organoaluminum oxy- compound; (C) an organoaluminum compound, if necessary; and an olefin polymer produced by prepolymerization; said prepolymerized catalyst having a bulk density of not less than 0.35 g/cm3 and a fluidity index of not less than 45, and an olefin polymerization process using the olefin polymerization catalyst. By using the olefin polymerization catalysts as described above, a fine-powdery polymer is hardly produced in the polymerization procedure, and a polymer showing excellent particle properties can be obtained. Moreover, the resulting olefin polymer does not stick to the wall of the polymerization reactor.
