Robert Allen Labonte (born May 8, 1964) is an American semi-retired professional stock car racing driver and current analyst for NASCAR on Fox. He also currently competes part-time in the SMART Modified Tour, driving the No. 18L for Hermie Sadler and Bill Stanley. Labonte is the 2000 NASCAR Winston Cup Series champion. He and his older brother, Terry Labonte, are one of only two pairs of brothers to have both won the Cup championships (along with Kurt Busch and Kyle Busch). He is also the uncle of former Xfinity Series race winner Justin Labonte.

A native of Corpus Christi, Texas, Labonte was the first driver (second overall) to have won both the Winston Cup championship (2000) and the Busch Series championship (1991) since Ned Jarrett and the first to do so under the revised points championship format. He also won the IROC title in 2001. Labonte is also the first driver to complete the NASCAR Triple Threat at the same track, by winning races at Martinsville in each of NASCAR's top three racing series.

Labonte was born on May 8, 1964, in Corpus Christi, Texas. He began racing in 1969 in quarter midgets in his home state of Texas, winning his first feature race one year later. From then until 1977, he drove in quarter-midgets throughout the United States, winning many races. In 1978, he advanced to the go-kart ranks but moved to North Carolina with his family following older brother Terry's advancement to the Winston Cup Series. In 1980, Bobby made his NASCAR International Sedan Series debut in Atlanta, finishing third. Two years later, he made his debut in the NASCAR Xfinity Series (subsequently rebranded as the Busch Series) at Martinsville Speedway, where he finished thirtieth. Following his graduation from Trinity High School in 1982, he worked as a fabricator on Terry's cars at Hagan Racing. Labonte returned to the Busch Series in 1985, running two races in a car he owned himself at Martinsville. In his first race, he finished 30th, bringing home only $220, but he improved to seventeenth place in his next race.

The next season, he helped prepare a car that his older brother would drive, which resulted in Terry's first ever NASCAR Busch Grand National Series pole position start and a subsequent second-place finish at Road Atlanta. Labonte's main success came driving late-model stock cars. In 1987, Labonte won twelve races at Caraway Speedway, clinching the track championship, in addition to working for Jay Hedgecock. The following season, he competed at Concord Motorsports Park, winning six times, and ran six more Busch races, finishing sixteenth at Darlington Raceway. The next season, he ran seven more races in the Busch Series and had his first top-five finish at Rockingham Speedway to go with two more finishes in the top ten.

By 1990, Labonte had finally earned enough money to race in the Busch Series on a full-time basis. He founded his own team and drove the No. 44 Oldsmobile. He was successful, winning two poles (both at Bristol Motor Speedway), scoring six top-fives, and seventeen top-tens. He ended up finishing fourth in the standings and was also voted the Busch Series' "Most Popular Driver."

In the next season, he continued his second-division success by winning the NASCAR Busch Series championship with two wins, ten top-fives, and 21 top-tens. He also won his first Busch Series race, at Bristol, then won again at O'Reilly Raceway Park in August.

In addition to his Busch Series schedule, he made two Winston Cup starts in a Bobby Labonte Racing car at Dover and Michigan International Speedway, finishing 34th and 38th, respectively. He won his first Busch Series title.

Labonte's 1992 season was a successful one, and he ended up winning three races (at Lanier, Hickory, and Martinsville respectively), but lost the championship title to Joe Nemechek by three points. That championship finish is, to date, the second-closest finish in the history of NASCAR's top three series (behind the tiebreaker between Tony Stewart and Carl Edwards in the Sprint Cup Series in 2011).
