Disclosed is a belt buckle assembly with magnetically interchangeable faceplates. The faceplate attaches to a base plate by a magnetically active plate on both the base plate and the faceplate. The base plate is concealed by the faceplate when the belt buckle is assembled and in use. The user's belt is attached by a belt loop at one end of the base plate and a post on the back side of the base plate which protrudes through a hole in the belt end opposite the belt loop.
