The present invention relates to a core-shell cobalt catalyst used for a Fischer-Tropsch synthesis reaction and a method for preparing the same. More particularly, it relates to a cobalt catalyst, which has a core-shell structure including a cobalt-supported and sintered alumina particle as a core and a zeolite powder coated on the surface of the alumina particle to a thickness of 50 &#x3bc;m or greater through mechanical alloying as a shell and is used to prepare hydrocarbons with high octane numbers through a Fischer-Tropsch synthesis reaction, and a method for preparing the same.
