Disclosed are a catalyst for carbonylation of dimethyl ether that has high catalyst activity and can be regenerated using a fluidized bed reactor, and a method for preparing the same. The catalyst for carbonylation of dimethyl ether includes a support having a first density; and ferrierite zeolite catalyst particles bound to a surface of the support via a polymer binder and having a second density smaller than the first density.
