An erroneous fitting prevention connector includes: a connector housing having a guide projection; and a mating connector housing having a rectangular tubular hood portion and a guide groove provided to be recessed on an inner wall surface of one side wall of the hood portion and extending along a fitting direction. At a front end portion of the other side wall parallel to the one side wall of the hood portion, an interference portion against which a housing front side end surface of the guide projection abuts when the connector housing is in a wrong insertion position, is formed. The interference portion has a contacted recess portion and an inclined contacted surface. The housing front side end surface has a contact surface that comes into contact with a bottom surface of the contacted recess portion, and an inclined contact surface that comes into contact with the inclined contacted surface.
