A retractable hitch is made to mount onto the rear of a towing vehicle, and lower the hitch ball to a desired level. A housing is attached to the towing vehicle, and has side walls and a bottom wall, the hitch bar is slidably mounted in the housing, and slides between a working position wherein an outer end carrying a hitch ball is extended from the vehicle, and a retracted position wherein the hitch ball is inside the housing. A spring-loaded lever holds the hitch ball in its retracted position, and is releasable to let the hitch bar out to its working position.
