An automatic trailer hitch assembly mounts a shank unit on the trailer and a receiving unit on the towing vehicle. The shank unit provides an elongated shank member which mounts a trailer ball at one end coupled to a conventional trailer hitch ball socket housing secured to the trailer and at the opposite end is formed to slide on funnel-like guide passages into the receiving unit. The receiving unit has a locking pin which can be latched into a position allowing entry of the shank member into the receiving unit and when the shank unit is properly positioned therein is automatically unlatched and moved into a position for locking the shank unit and receiving unit together. The locking pin when restored to the latched position enables the shank unit to be withdrawn from the receiving unit.
