Marn Grook or marngrook, from the Gunditjmara language for "game ball", is a collective name given to a number of traditional Indigenous Australian recreational pastimes believed to have been played at gatherings and celebrations of up to fifty players. It is distinct from the indigenous ball game Woggabaliri which is believed to be the subject of William Blandowski's engraving "never let the ball hit the ground" (see picture on right).
