A golf bag is provided with a support frame capable of supporting securely the golf bag on a surface of the golf course regardless of the surface feature of the golf course. The support frame comprises two expandable legs, with each having an elastic element capable of compressing in response to a surface feature of the golf course. The support frame further comprises a movable base which is linked with the two expandable legs by a link rod. The two expandable legs are actuated by the link rod to expand in opposite directions at such time when the movable base is located on the surface of the golf course. The golf bag is thus securely supported on the surface by the two expandable legs and the movable base, which form together three supporting points.
