Abstract: Provided are a novel metallocene compound, a catalyst composition including the same, and a method of preparing an olefin-based polymer using the same. The metallocene compound according to the present invention or the catalyst composition including the same may be used for the preparation of an olefin-based polymer, may have excellent polymerization ability, and may produce an olefin-based polymer having a high molecular weight. In particular, when the metallocene compound according to the present invention is employed, an olefin-based polymer having a high molecular weight may be polymerized because the metallocene compound shows high polymerization activity even when it is supported on a support and maintains high activity even in the presence of hydrogen because of its low hydrogen reactivity.
