A collapsible goal frame for ball games has a frame composed by a vertical n-shaped frame, an upper horizontal n-shaped frame, a lower horizontal n-shaped frame and two vertical supporting poles; in particular, connecting tubes are contraposed between the upper horizontal n-shaped frame and the lower horizontal n-shaped frame; the present invention is characterized that two sides of the vertical n-shaped frame are respectively disposed with a 180° bendable joint; on two sides of the upper horizontal n-shaped frame and the lower horizontal n-shaped frame are respectively disposed with a 90° bendable joint; after the supporting pole is detached, the bendable joints of the upper horizontal n-shaped frame and the lower horizontal n-shaped frame are folded toward each other; then the bendable joints on two sides at the center of the vertical n-shaped frame are bent forwardly and downwardly to form a collapsed structure slightly in a W-shape.
