In the representative embodiments of the new and improved trailer hitches disclosed herein, a base is secured to the rear of a towing vehicle for carrying an upright coupler ball aligned along a generally-vertical axis. Members are arranged above the base for providing upwardly-facing coupler-supporting surfaces extending outwardly from each side of the coupler ball as well as a rearwardly-facing upright coupler-positioning surface spaced ahead of the vertical axis and inwardly-facing opposed guide surfaces respectively spaced on opposite sides of the vertical axis for cooperatively guiding a trailer coupler downwardly onto the coupler ball after the coupler has been slid across either of the supporting surfaces.
