The Dinamo Zagreb–Red Star Belgrade riot was a football riot which took place on 13 May 1990 at Maksimir Stadium in Zagreb, SR Croatia, then part of SFR Yugoslavia, between the Bad Blue Boys (supporters of Dinamo Zagreb) and the Delije (supporters of Red Star Belgrade). The incident took place just weeks after Croatia's first multi-party elections in almost fifty years in which the parties favouring Croatian independence had won the majority of votes. The riot resulted in over sixty people wounded, including some stabbed, shot or poisoned by tear gas.

Many fans of both Red Star and Dinamo would fight in the subsequent wars, with some of the Delije joining Arkan's paramilitary organization. Both Dinamo and Red Star had violent undertones and essentially functioned as paramilitary organizations, rather than mere football fan clubs. The clash Up to several hours before the kick-off, skirmishes were reported around Zagreb between Red Star fans (Delije) and Dinamo fans (Bad Blue Boys), which then carried over to Maksimir Stadium. Provoked by stones reportedly being thrown by the Bad Blue Boys, the Delije, situated in the stadium's segregated area reserved for visiting fans, began to tear up the advertising plates and eventually made their way to Dinamo fans. The Delije proceeded to attack them with torn-off seats after reportedly chanting
