Gregory S. Rayl (pronounced "rail", born November 20, 1963) is an American professional stock car racing driver and crew chief who last worked for Reaume Brothers Racing as the crew chief of their No. 33 Ford F-150 in the NASCAR Craftsman Truck Series driven by Memphis Villarreal. He has also previously competed in the Truck Series as well as what is now the ARCA Menards Series West as a driver. Most of his 32 career starts in the West Series came as an owner-driver for GSR Racing.

A native of Salida, California, Rayl's first NASCAR action came in 1993 with the NASCAR Featherlite Southwest Tour at Stockton 99 Speedway; he finished 16th after crashing on lap 49.^[1] In 2008, he began racing part-time in the NASCAR Camping World West Series; two years later, he ran a full schedule in the now-K&N Pro Series West in the No. 07 Ford, finishing 12th in the standings.^[2] At season's end, Rayl received the NASCAR Sportsmanship Award. He formed his own team, GSR Racing, in 2011, racing the full schedule and finishing 11th in points. For the 2012 season, he stepped back to serve as GSR's crew chief for drivers Cassie Gannis and Trevor Cristiani.^[3][4]

In 2019, he joined Reaume Brothers Racing in the NASCAR Gander Outdoors Truck Series as a crew chief for their No. 34 team.^[5] In June, he made his Truck debut in the CarShield 200 at World Wide Technology Raceway at Gateway for Jennifer Jo Cobb Racing, but finished last after wrecking on lap two.^[6] He made one more start as a driver, this time for the Reaume team, in their No. 32 at the Canadian Tire Motorsport Park road course race. It was a start-and-park field filler entry at that race as a result of only 29 trucks showing up instead of the usual 32. For the rest of that year, he crew chiefed one of Reaume's trucks (the No. 32, 33, or 34) in each race.

In 2023, Rayl returned to RBR as the crew chief of their No. 33 truck driven by Mason Massey. On March 21, NASCAR suspended Rayl and two of the truck's pit crew members for three races after the truck lost its ballast during the race at Atlanta.^[7]

On October 14, 2012, he married Nancy J. Rayl in El Dorado Hills, California.^{[citation needed]}
