A golf bag base includes a base body, which has a bottom consisting of a sloping surface and a planar surface; a base case to enclose the base body, which comprising a side frame; a sliding shaft provided at a joint position between the sloping surface and the planar surface of the bottom of the base body; and two sliding grooves provided in two symmetrical positions of the side frame of the base case, and two ends of the sliding shaft are protruded from two sliding grooves, respectively. Thus, a largest possible contact area between the golf bag base and the ground can be achieved so as to ensure a stable placement of the golf bag. In addition, a more aesthetical and pleasing appearance can also be attained.
