A slidable trailer hitch apparatus comprises a trailer hitch head operable to receive a cooperating portion of a trailer, the trailer hitch head adapted to be slidable and rotatable relative to the vehicle about an axis of rotation, first and second parallel spaced part guides fixedly located relative to the vehicle, and a body affixed to and rotatable with the trailer hitch head, the body having a center of rotation about the axis and a distal surface adapted to engage either of the first or second guides when the body is rotated relative to the first and second guides. The engagement of the distal surface upon either of the first or second guides displaces the center of the body and the trailer hitch head parallel to the first or second guide when the trailer hitch head is rotated relative to the first and second guides.
