The 1973 USAC Championship Car season consisted of 16 races, beginning in College Station, Texas on April 7 and concluding in Avondale, Arizona on November 3. The first race of the season, in Avondale, Arizona on March 17, was postponed by rain and eventually cancelled due to infrastructure damage caused by the rain and scheduling conflicts. Bob Criss was killed in a private test at Phoenix before he could enter another event. He was 35 years old. The USAC National Champion was Roger McCluskey and the Indianapolis 500 winner was Gordon Johncock.

In this tragic season, two drivers were killed at the Indianapolis Motor Speedway. Art Pollard died in an accident while practicing for the Indy 500 while Swede Savage, who crashed during the race, died by complications one month later. Another driver, Salt Walther, suffered serious burns surviving a crash at the start of the race. In response to those accidents, USAC revised the rules in time for the Pocono 500. The rear wing width was cut back from 64 inches to 55, fuel tank capacity was drastically reduced (from 75 gallons to 40) and the allowable fuel to be consumed in a 500-mile race was reduced from 375 gallons to 340.
