Richard Petty Motorsports (RPM) was an American professional stock car racing team that competed in the NASCAR Cup Series. The team was founded as a result of the merger between Gillett Evernham Motorsports (GEM) and Petty Enterprises, with former Montreal Canadiens and Liverpool F.C. owner George Gillett having a controlling interest in the organization. In late 2009, the team merged with Yates Racing and consequently switched to Ford for the 2010 season. Evernham had no involvement in the team by this time.

Petty Enterprises was a NASCAR racing team based in Level Cross, North Carolina, USA. It was founded by Lee Petty with his two sons Richard Petty and Maurice Petty. The team was later owned by Richard Petty, his son Kyle Petty and Boston Ventures. At the time of its folding the team operated the No. 43 and No. 45 Dodge Chargers in the NASCAR Sprint Cup Series. Petty Enterprises ran from 1949 until 2008. The team closed shop in January 2009 and merged with Gillett Evernham Motorsports after sponsorship could not be found for any of the cars in the Petty stable; the merged team took the name Richard Petty Motorsports, adopting a logo similar to that of Petty Enterprises' logo. In 2021, Richard Petty Motorsports became Petty GMS Motorsports, and in 2023 the team rebranded as Legacy Motor Club.
