  Disclosed is an olefin polymerization catalyst comprising a transition metal selected from metals of Groups IIIA including the lanthanide series, IVA, VA, VIA, VIIA and VIII of the Periodic Table of the Elements, and ligands L¹ and L² bonded thereto, wherein a combination of L¹ and L² is (1) a combination of ligand L¹ which is a group containing at least one phosphorus-containing group and ligand L² which is a ligand having a σ-bond, or a ligand having a σ-bond and a bond selected from at least one π-bond and at least one lone electron pair donative bond; (2) a combination of ligand L¹ which is a 5-membered heterocyclic pentadentate ligand having one or more heteroatoms and ligand L² which is a ligand having a σ-bond, or a ligand having a σ-bond and a bond selected from at least one π-bond and at least one lone electron pair donative bond, provided that when the pentadentate ligand contains only one heteroatom, L² is a ligand having a σ-bond, or a ligand having a σ-bond and at least one lone electron pair donative bond; and (3) a combination of ligand L¹ which is a trispyrazolyl tridentate ligand and ligand L² which is an alkapolyenyl ligand, and wherein each L¹ contains an element of Group VB or Group VIB. The catalyst of the present invention has extremely high catalytic activity for an olefin polymerization reaction as compared to conventional olefin polymerization catalysts.
