Gregory Jack Biffle (born December 23, 1969 in Vancouver, Washington) is a NASCAR NEXTEL Cup Series driver. He now lives in Mooresville, North Carolina. He has also left a lasting impression as the "Most electrifying Craftsman Truck Series driver of the late 90s".

Biffle gained national attention when he raced in the NASCAR Winter Heat series on ESPN2 in the winter of 1995/1996. Former ESPN announcer and NASCAR champion Benny Parsons told Jack Roush that there was no way he could pass up the chance to hire Biffle, and that if he did he would regret it while watching Biffle win races for another team owner .

Starting in the Craftsman Truck Series, Biffle first won Rookie of the Year in 1998 for Roush Fenway Racing. In 2000, he won the series title in the #50 Grainger Ford F-150, which was his first championship in one of NASCAR's three major series. In 2001, he ran four more races for Jack Roush in the #99 Eldon Ford F-150. His last truck start was in 2004 for Tom Mitchell in the #44 Ford Racing Ford F-150 at Homestead-Miami Speedway.

Biffle first drove two races in 1996 for Dick Bown in the #51 Barbasol Chevrolet Monte Carlo. Biffle joined the NASCAR Busch Series full-time in 2001. He won the series rookie of the year award. He had five wins and finished fourth in points. In 2002 Biffle brought Roush another championship, this time in the NASCAR Busch Series. His four wins, twenty top fives and twenty-five top tens earned him the championship victory over fellow Busch Series regulars Jason Keller and Scott Wimmer. Biffle has continued to drive in the Busch Series every season since then. Biffle ran only part-time in 2003, but contended for the NASCAR Busch Series championship again in 2004, finishing third behind future NEXTEL Cup regulars Martin Truex Jr. and Kyle Busch. Running part-time again in 2005, Biffle again placed in the top ten in NASCAR Busch Series points standings, despite running only twenty-seven races, eight races fewer than the full season.

In 2002, Biffle drove his first NASCAR NEXTEL Cup Series race at California Speedway in the #16 Volvo Trucks Ford Taurus for Roush Fenway Racing. He also drove for Andy Petree Racing in the #55 Schneider Electric Chevrolet Monte Carlo and for Petty Enterprises in the #44 Georgia Pacific Dodge Intrepid. In total, Biffle ran 7 races with 3 top-5 starts and a best finish of 13th.

Biffle started competing full time in NASCAR's top circuit in 2003, and he finished in 20th place in the final NEXTEL Cup series points. He earned his first win at the Daytona International Speedway. He finished second to Jamie McMurray for Raybestos Rookie of the Year. His car was sponsored by Grainger Industrial Supply, Co., who had previously sponsored him in his Busch and truck series efforts.

Greg Biffle showed steady improvement over the 2004 season as he earned two more race wins en route to a 17th place finish in the points.

2005 was Biffle's breakout season. He finished the season tied with teammate Carl Edwards for second in the NASCAR NEXTEL Cup championship, thirty-five points behind champion Tony Stewart. Biffle won the tie-breaker for second because of his six race victories, the most of any driver in the Nextel Cup Series that season.

In 2006, Biffle won twice, at Darlington Raceway and Homestead-Miami Speedway. Biffle struggled considerably during the year, finishing 24th at Pocono Raceway, 33rd at the Brickyard and 38th at Watkins Glen International.

The Army National Guard served as the primary sponsor from 2004-2006. Other sponsors included Post-it/3M, Jackson Hewitt Tax Services, Subway, Charter Communications and Prism Guard Shield.

For 2007, Biffle will drive the #16 Ameriquest/3M Ford Fusion for Roush Fenway Racing. Biffle is currently signed with Roush Fenway Racing until 2008.
