A hitch coupling for mounting on a trailer for engagement with a hitch ball mounted on a towing vehicle features a hitch ball receiving socket, a guide body connected to the hitch ball receiving socket and extending to one side thereof and a mounting body extending from the guide body at an end thereof opposite the hitch ball receiving socket. The guide body features two generally vertical side walls being horizontally spaced apart adjacent the one side of the hitch ball receiving socket and diverging horizontally away therefrom and a ramping surface defined between the two generally vertical side walls extending upward away from the mounting body toward the hitch ball receiving socket. The sloped surface encourages mating of the hitch and socket under the weight of the trailer. A rear wall of the socket extends downward toward the ramping surface to help prevent inadvertent withdrawal of a hitch ball.
