A ball rebound apparatus includes a part-cylindrical rebound panel with attachment flanges at the lateral extremities thereof and with parallel end walls closing the axial extremities thereof. The panel is mountable on and between two adjustable, triangular support frames, each having a base rail connectable to the ground or other underlying support surface, a mounting rail to which the rebound panel is attached and a support rail connectable to the base rail at various locations for changing the inclination of the mounting rail. The rebound panel is reversible so that it can be mounted with either its concave surface or its convex surface disposed forwardly. It is also mountable with its cylindrical axis disposed in a vertical plane, with the attachment flanges secured to the support frame, or with its cylindrical axis disposed in a horizontal plane, with its end walls secured to the support frame.
