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