An olefin polymerization catalyst enabling the production of olefin polymers with excellent polymerization activity and a process for polymerizing an olefin by the use of the catalyst. The catalyst comprises a transition metal amide compound of general formula (I) ¢wherein M1 is Ti or the like; R1 is alkyl, (substituted) phenyl or the like; R2 is -C(R5)2C(R6)mC(R5)2- or -C(R5)2-X1-C(R5)2- (wherein X1 is a silicon-containing group or the like; and R5 and R6 are each hydrocarbyl or the like); and R3 is hydrocarbyl, halogeno or the like!, and at least one compound selected from among organoaluminumoxy compounds, ionizing ionic compounds and organometallic compounds. The process enables the production of olefin polymers with high polymerization activity to give olefin polymers free from residual odor, and comprises conducting the (co)polymerization of olefins in the presence of a catalyst comprising a transition metal amide compound of the general formula: (R2N)kM2X2j-k (wherein M2 is Ti, Zr or the like; j is the valence of M2; k is 1 to j; R is hydrogen, hydrocarbyl or the like; and X2 is halogeno, hydrocarbyl or the like) and an organoaluminumoxy compound, which is added to the polymerization system in a state slurried in an aliphatic or alicyclic hydrocarbon.
