Abstract: A golf bag canopy adapted to be mounted to a golf cart roof, and particularly to the rear edge of a golf cart roof. The canopy assembly essentially includes an elongated awning track, a pair of J-bar frame members, one of which is attached to either end of the awning track, a U-shaped bow frame member attached to the ends of each J-bar for pivotal movement with respect thereto, and a pliable cover having a leading edge securely attached to the awning track and a body draped over and supported by the U-shaped bow. By pivotally moving the U-shaped bow between its terminal positions, the cover correspondingly moves between covered and uncovered relation to the golf bag compartment of a golf cart. The cover may be positioned in covered relation relative to the golf bag cover during times of inclement weather, or may be positioned in uncovered relation relative to the golf bag compartment when accessing a club.
