The 2010 NASCAR Nationwide Series was the 29th season of the NASCAR Nationwide Series, the second-tier professional stock car racing series sanctioned by NASCAR in the United States. Beginning at Daytona International Speedway, the season included thirty-five races, which ended with the Ford 300 at Homestead Miami Speedway. Brad Keselowski clinched the drivers' championship during the O'Reilly Auto Parts Challenge at Texas Motor Speedway, two races before the season finale at Homestead, while Joe Gibbs won the owners' championship (for the No. 18 car, driven by Kyle Busch and Brad Coleman). Toyota won the manufacturers' championship with 240 points.

During the 2009 off-season, NASCAR announced few calendar changes, including moving the race at Memphis Motorsports Park to Gateway due to the closure of Memphis. The short track of Milwaukee was also replaced with the road course at Road America, which hosted its first NASCAR race since a Cup race in 1956.

This was also the last season where Cup Series drivers could run for points in the series. NASCAR implemented this change after Cup drivers won the Busch/Nationwide championship over the series regulars for the fifth straight year in 2010.
