1993 NASCAR Winston Cup Series

The 1993 NASCAR Winston Cup Series was the 45th season of professional stock car racing in the United States and the 22nd modern-era Cup season. The season began on February 7 and ended on November 14. Dale Earnhardt of Richard Childress Racing won the title, the sixth of his career.

1993 was marked by the deaths of two Winston Cup drivers, though neither were on-track in any form. 1992 Champion Alan Kulwicki was killed on April 1 in a plane crash near Blountville, Tennessee. He was travelling to Bristol International Raceway in a corporate jet belonging to his sponsor, Hooters. Davey Allison died on July 13, a day after a helicopter crash at Talladega Superspeedway left him with a severe head trauma. The accidents robbed the sport of two of its brightest young stars and denied Kulwicki the chance to defend his 1992 title.

The season also saw the introduction of electronic scoring, giving instantaneous interval numbers.

This was the first season without NASCAR legend Richard Petty since 1957.
