The Formula One Indoor Trophy or Trofeo Indoor Formula One was a non-championship Formula One sprint held at the Bologna Motor Show between 1988 and 1996. Despite having Indoor in the name of the race, the race was staged outside. The first race was won by Luis Pérez-Sala. The last running of the event was the last non-championship Formula One competition and was won by Giancarlo Fisichella in a Benetton-Renault.
