Regan[a] Lee Smith (born September 23, 1983) is an American former professional stock car racing driver and a current pit reporter for Fox NASCAR.

In 2001, he began driving in the USAR Hooters Pro Cup Series, winning four consecutive poles.

He also made his Busch Series debut at Memphis Motorsports Park for Ed Whitaker, starting 16th but finishing 39th after a wreck.

50 Enzyte Chevrolet Monte Carlo for Michael Holigan for three races and appeared in a few episodes of The Reality of Speed on Spike, his best finish 26th at Chicagoland Speedway, before that team suspended operations.

Despite a streak of six races where he did not qualify worse than twelfth, including three thirteenth-place runs, he was released from the team.

Smith made his official Nextel Cup debut at the Food City 500 at Bristol Motor Speedway, finishing 25th in NASCAR's first Car of Tomorrow race.

The team operated with little to no sponsorship (Principal Financial Group was the main sponsor), but managed to stay in business the entire season.

On May 7, 2011, at the Showtime Southern 500 at Darlington Raceway, Smith won his first Sprint Cup race, holding off Carl Edwards at the end.

Smith fended off Edwards for two restarts to claim the first cup win of his career at Darlington Raceway.

It was only the third time a driver had won his first Sprint Cup race at Darlington Raceway, the first being Terry Labonte in 1980, the second being Lake Speed in 1988.

At the 2011 Brickyard 400, Smith had enough fuel to end with a solid 3rd-place finish by passing Jamie McMurray on the last lap, for his second top five of 2011.

Also a strong run at New Hampshire Motor Speedway proved that Smith was ready for the Sprint Cup Series with another top ten position.

At the fall race at Talladega Superspeedway, Smith was accidentally turned by Mark Martin and smashed extremely hard head on into the wall.

In 2012 when the Daytona 500 frustrated many fans and NASCAR officials because of a long rain delay on the planned date, a rain delay in the morning, and then the bizarre fire red flag delay caused by Juan Pablo Montoya's crash into a jet dryer in turn 3 on lap 160, Smith told the public he was so happy and excited for the first time in his career to leave Daytona that night.

After the race Smith maintained that he did not intentionally crash her while Patrick believed he did and both left Bristol without any penalties.

[3] In his last start for FRR, in the fall race at Talladega, Smith had a fifth-place finish after clearing a 23-car crash in turn 4 on the last lap.

51 Chevrolet at Phoenix Racing, but Smith was announced on October 11, 2012, as the replacement driver for Dale Earnhardt Jr. in the works team's No.

88 Chevrolet for the Charlotte and Kansas Chase races after Earnhardt was diagnosed with a concussion after his testing crash at Kansas Speedway in August and after involvement in the same last lap crash during the Good Sam Club 500 at Talladega on October 7, 2012, so for these two races, Smith was replaced in the No.

Qualifying 26th and performing well during both practice sessions, Smith had a top ten car before the engine failed for the first time on the No.

In the following race at Kansas, Smith performed well, and managed to muster a top ten finish.

On August 15, Smith won the Nationwide Children's Hospital 200, at Mid-Ohio Sports Car Course, passing the leader, Alex Tagliani, in the last lap after slight contact while racing for the lead.

[15] On October 3, Smith won his second race in 2015 at Dover, after holding off Kyle Busch and Denny Hamlin.

On October 17, Smith stated that he would not return to JR Motorsports for 2016 and expected to join a team that is competing in the Cup Series in 2016.

[18] Smith ran the full 2016 schedule for TBR with the exception of the Teenage Mutant Ninja Turtles 400, for which he was replaced by Ty Dillon as he flew to North Carolina to await the birth of his child.

[19] Smith lost his ride after it was announced on November 17 that Tommy Baldwin Racing would no longer compete full-time after the season was over.

[20] On February 8, 2017, Smith joined RBR Enterprises to run 10–12 races in the Truck Series.

[24] In June, Smith became a color commentator for Fox NASCAR's broadcast of the Xfinity Series race at Iowa Speedway.

On November 29, 2017, Fox NASCAR announced Smith would become a pit reporter for Cup and Xfinity races in 2018.

Smith received the blessing of his Fox NASCAR superiors to take the ride with LFR.

[27] Smith said that working the 2018 season on television helped him to know the entire NASCAR community better because he was not bound by team alliances anymore and could talk to anyone in the garage.
