A slidably positionable trailer hitch guide apparatus is set forth wherein a trailer hitch guide is formed with a plurality of vertically oriented flanges formed with a connecting plate overlying a slot formed in each vertical flange wherein the slots are aligned with one another and the plate is formed with a "U" shaped recess for accepting a securement ball for use in cooperation with a connecting trailer socket. The vertical flanges each have secured thereto a directing flange formed at an obtuse angle relative to said vertical flange with an underlying connecting flange at an obtuse angle to said plate. A plurality of stabilizing webs are orthogonally and outwardly projectingly secured to each vertical flange for stabilizing the guide apparatus relative to an automotive type bumper having secured thereto the securement ball.
