A hitch guide is a device to aid the driver of a pickup truck in mounting a gooseneck trailer hitch onto the hitch ball mounted in the bed of a pickup truck. the present device has a strap mounted between tow end pieces which in turn mount on the side rails of a pickup truck bed to that the end pieces may be moved along the length of the pickup truck bed for adjustment purposes. A marker, mounted on the strap, may be adjusted laterally between the two pickup bed rails. When the strap and marker are properly adjusted, the pickup truck when backed up to the mounting pole of a gooseneck trailer so that the marker is just touching the mounting pole will be oriented so that the mounting pole and gooseneck trailer hitch are aligned directly over the hitch ball in the pickup truck bed.
