William Caleb Yarborough (March 27, 1939 – December 31, 2023) was an American NASCAR Winston Cup Series driver and owner, businessman, farmer, and rancher. He was the first driver in NASCAR history to win three consecutive championships, winning in 1976, 1977, and 1978. He was one of the preeminent stock car drivers from the 1960s to the 1980s and also competed in IndyCar events. His fame was such that a special model of the Mercury Cyclone Spoiler II was named after him.
His 83 wins tie him with Jimmie Johnson for sixth on the all-time NASCAR Cup Series winner's list (behind Bobby Allison, who has 85 and Darrell Waltrip, who has 84). His 14.82% winning percentage is the ninth best of all-time and third among those with 500 or more starts. Yarborough won the Daytona 500 four times; his first win coming in 1968 for the Wood Brothers, the second in 1977 for Junior Johnson, and back-to-back wins in 1983 and 1984 for Ranier-Lundy Racing. Yarborough was a three-time winner of the National Motorsports Press Association Driver of the Year Award (1977, 1978, 1979).
