The purpose of the present invention is to provide a hydrogenation catalyst, which can produce an olefin polymer having a higher molecular weight, and a process for producing an olefin polymer so that an olefin polymer having a higher molecular weight can be produced, by controlling hydrogen concentration in a polymerization reaction system efficiently in polymerizing an olefin in the presence of hydrogen. There is provided a hydrogenation catalyst formed by contacting the undermentioned component (A), the undermentioned component (B), and the undermentioned component (C). There is further provided a process for producing an olefin polymer characterized by polymerizing an olefin in the presence of hydrogen, the undermentioned component (A), the undermentioned component (B), and the undermentioned component (D). Component (A): a titanocene compound Component (B): a silicon compound represented by the undermentioned general formula [1] Si(OR1)4 [1] (In the formula, R1 stands for a hydrocarbon group having 1 to 20 carbon atoms, and four R1 may be same or different respectively.) Component (C): an alkyl metal compound Component (D): a catalyst for olefin polymerization
