Abstract: The present invention relates to a zeolite catalyst for preparing light alkene by dehydrogenation of light alkane including a cocatalyst metal selected from tin (Sn), germanium (Ge), lead (Pb), gallium (Ga) and indium (In), and a preparation method of the same. The catalyst of the present invention is prepared by using the zeolite having a relatively high pore diameter, a structure of at least 12-membered ring, and a low acidity due to a SiO2/Al2O3 ratio of at least 50, so that it can suppress the inactivation of a catalyst caused by pore clogging due to the formation of coke. Therefore the catalyst of the present invention can be effectively used as a catalyst for the preparation of light alkene by dehydrogenation of light alkane.
