Ralph Dale Earnhardt Jr. is an American stock car racing driver, team owner and broadcaster. A third generation driver, he is the son of 7-time NASCAR Cup Series champion Dale Earnhardt and relative to many former and current drivers in the NASCAR ranks. Since retiring from full-time competition after the 2017 season, he has competed part-time in the NASCAR Xfinity Series, driving the No. 88 Chevrolet Camaro for his JR Motorsports team.

Dale Earnhardt, Inc. (DEI) is a former race team founded by Dale Earnhardt and his wife, Teresa Earnhardt, to compete in the NASCAR Cup Series, the highest level of competition for professional stock car racing in the United States. From 1998 to 2009, the company operated as a NASCAR-related organization in Mooresville, North Carolina, United States. Earnhardt was a seven-time Winston Cup champion. He died in a crash on the final lap of the 2001 Daytona 500. Despite his ownership of the DEI racing team, Earnhardt never drove for his team in the Winston Cup; instead, he raced for his long-time mentor and backer Richard Childress at RCR. In the late-2000s, DEI suffered critical financial difficulties after drivers Dale Earnhardt Jr. and Michael Waltrip, and sponsors Anheuser-Busch, National Automotive Parts Association and United States Army left the team; DEI consequently merged with Chip Ganassi Racing in 2009, moving their equipment into the latter's shop, while the former's closed down. Chip Ganassi Racing's NASCAR operations was subsequently purchased by Trackhouse Racing Team in 2021.
