A vertically adjustable trailer hitch includes a stationary portion possessing a transversely extending mounting stub dimensioned for insertion into a trailer hitch tongue. A plurality of reinforcement struts include mounting edges disposed in spaced relation to the mounting stub and adapted for welding to the trailer hitch tongue. A vertically elongated rectangular guide plate includes a plurality of pairs of aligned apertures spaced along opposite longitudinal edge portions. A longitudinally extending guide rib extends vertically along a front face of the guide plate. A stop block secured on a top edge of the guide plate overhangs the guide rib. A vertically reciprocal slider includes opposite channel edge portions surrounding longitudinal edge portions of the guide plate. A guide groove on the slider is disposed in engagement with the guide rib. A pair of latch pin assemblies on the slider are selectively engageable with the apertures of the guide plate to secure the slider in a selected vertically adjusted position. A trailer hitch coupler mount extends outwardly from a front face of the slider.
