The 1980 CRC Chemicals Rebel 500 was a NASCAR Winston Cup Series racing event that was held on April 13, 1980, at Darlington Raceway in Darlington, South Carolina. Forty-five thousand fans would attend the event, interrupted by 0.31 inches or 7.9 millimetres of precipitation, shortened to the shortest race in what is now the Cup Series by percentage in Darlington history (51.50%, 189 laps, which is six laps more than an official race, which would be 184 laps), as the race was shortened because of impending darkness (Darlington did not add lights until the 2004 Southern 500).
