The trailer hitch enclosure device includes a base support including a first elongate member and a second elongate member attached together. The first elongate member is positioned on top edges of and extending between side walls of the truck bed and the second elongate member abuts a top edge of a back wall of the truck bed. Four panels are hingedly coupled to the base support, such that a back pair is coupled to the second elongate member and a second pair is coupled to the first elongate member. The panels have a size adapted for collectively covering the truck bed. The panels attached to the first elongate member have a slot therein facing each other and defining an opening for receiving the hitch of a fifth wheel trailer.
