A trailer hitch assembly for allowing a user to simultaneously extend and pivot the distal end of the trailer hitch to position the hitch ball in a desired position. The inventive device includes a support frame attachable to a vehicle, a telescoping structure pivotally attached within the support frame, and a spring-loaded locking pin attached to the support frame for selectively engaging the telescoping structure for preventing extension and pivoting movement. The telescoping structure comprises a receiver member pivotally attached within the support frame, an extending member slidably positioned within the receiver member for supporting a conventional hitch ball, a lock aperture within the extending member for catchably receiving the locking pin, at least one guide slot within the receiver member, and at least one guide pin for sliding within the at least one guide slot. A pair of stopper members are preferably secured to the perimeter of the extending member for engaging the edge of the receiver member thereby preventing damage to the locking pin. A wear plate is preferably attached to a lower plate of the support frame for providing a reduced friction surface for the receiver member to pivot upon. A wear liner is preferably within the lumen of the receiver member for providing a reduced friction surface for the extending member to extend inwardly and outwardly upon. The locking pin preferably includes a handle for allowing the user to grasp manually. A pair of wing members are attached to the receiver member for preventing the locking pin from extending beside the receiver member during pivoting of the receiver member.
