Abstract: The present invention relates to a method for preparing a hybrid supported metallocene catalyst. More specifically, the present invention relates to a method for preparing a hybrid supported metallocene catalyst by using two or more different types of metallocene compounds. One type of the metallocene compounds shows a high polymerization activity even when it is supported, and thus the catalyst has an excellent activity and can be utilized in the polymerization of olefinic polymers having ultra-high molecular weight. Based on the hybrid supported metallocene catalyst obtained according to the preparation method of the present invention, an olefinic polymer having high molecular weight and the desired physical property can be prepared.
