The NASCAR Xfinity Series Drivers' Championship is awarded by the chairman in NASCAR to the most successful Xfinity Series racing car driver over a season, as determined by a points system based on race results. The Drivers' Championship was first awarded in ￼￼1950, to ￼￼Mike Klapak. The first driver to win multiple Championships was Mike Klapak in 1950, 1951 and 1952. The current Drivers' Champion is Chris Buescher who won his first NASCAR Xfinity Series championship in 2015.
NASCAR does not officially declare the Champion until the end of the season, but a driver is said to have "clinched" the Championship after it is no longer possible for another to obtain more points than he has, even if the former driver were to not compete in the remaining races of the season, and the latter to score the maximum number of points possible. The earliest in a season that the Drivers' Championship has been clinched was in 2006, when Kevin Harvick secured the title with four races remaining.
Overall, Jack Ingram has the most championship wins of five, while Rene Charland has four, Mike Klapak and Red Farmer has three championships, and twenty-six different drivers have won the Championship, with Sam Ard, Jack Ingram, Larry Pearson, Randy LaJoie, Dale Earnhardt, Jr., Kevin Harvick, Martin Truex Jr., and Ricky Stenhouse Jr. holding the record for most titles, at two. Ard, Pearson, LaJoie, Earnhardt, Jr., Truex Jr., and Stenhouse Jr. all have the record for most consecutive Drivers' Championships, with two consecutive championships.
