Abstract: A golf bag accessory is provided for supporting a golf bag in an upright configuration. The accessory is mounted beneath the base member of a golf bag and includes blade-like elements that are displaceable between an inoperative position in which they are disposed substantially entirely within the outer perimeter of the base member of the bag and an operative position in which they extend radially beyond the outer perimeter of the base member of the bag. In this operative position the blade-like elements effectively enlarge the diameter of the base member and thereby render the bag self-supporting in its upright configuration.
