William Darrell "Bubba" Wallace Jr. is an American professional stock car racing driver. He competes full-time in the NASCAR Cup Series, driving the No. 43 Chevrolet Camaro ZL1 1LE for Richard Petty Motorsports. Previously, Wallace was signed as a development driver for Joe Gibbs Racing where Wallace competed in the Camping World Truck Series, driving the No. 54 Toyota Tundra for Kyle Busch Motorsports. He also raced in the Xfinity Series, driving the No. 6 Ford Mustang of Roush Fenway Racing, from 2015 to mid 2017. Wallace is noted for being one of the most successful African American drivers in the history of NASCAR.

Wallace started racing in the Bandolero and Legends car racing series, as well as local late model events, at the age of nine. In 2005, he won 35 of the Bandolero Series' 48 races held that year; in 2008 he became the youngest driver to win at Franklin County Speedway in Virginia.

In 2019, Wallace revealed that he dealt with and continues to deal with depression for most of his racing career. After others reached out to him to thank him for bringing awareness to depression, Wallace said he did not know it was such a widespread problem; for him, being depressed was an honest answer to a media question.

Born to a black mother and white father, Wallace is the son of Darrell Wallace Sr. and Desiree Wallace. His father is the owner of an industrial cleaning company, and his mother is a social worker who ran track at the University of Tennessee.
