The 1972 NASCAR Winston Cup Series was the 24th season of professional stock car racing in the United States and the 1st modern-era NASCAR Cup series season. The season began on Sunday January 23 and ended on Sunday November 12. Richard Petty won his second consecutive Winston Cup Championship and fourth overall. Larry Smith was named NASCAR Rookie of the Year. This season is considered to be the first of NASCAR's "modern era". The number of races was reduced from 48 to 31, all dirt tracks were removed from the schedule, and a minimum race distance of 250 miles (402 km) was established for oval tracks. (The shortest scheduled race in the modern era was the 2021-2023 Food City 250 at Bristol Motor Speedway of 133.25 miles, on dirt; the shortest Cup Series race since the rule change was the 1992 Watkins Glen race, which was 125.127 miles (51 laps) because of rain in an era before NASCAR began racing in rain.)
