Brian Allen Keselowski[1] (born September 2, 1981[2]) is an American professional stock car racing driver, crew chief, and spotter.

[3] He graduated from Rochester High School in 1999, taking night classes to allow him to work as a jackman for the family racing team, K-Automotive Motorsports; he flew to the racetrack directly from his senior prom to assist in competition.

[3] He began his racing career competing in super late model events, winning rookie-of-the-year at Auto City Speedway in 2000.

The next season, the team was purchased by his family,[3] and he ran seven races including a string of five consecutive top-ten finishes.

In 2006, Holloway Motorsports and Dusty's Collision became the sponsors of his car, and he won his first race at Berlin Raceway.

He had intended to compete at Auto Club Speedway in Fontana, California, but was not approved to run at the 2-mile (3.2 km) track; his brother Brad drove the race instead, jump-starting his career.

[3] For 2009, Keselowski attempted his first full-time season for Whitney and K-Automotive Motorsports, which renumbered its car with the No.

The primary sponsor for Keselowski's car during the 2009 CarQuest Auto Parts 300 was the Detroit Red Wings National Hockey League team; Keselowski ran eighteen races, but stepped aside for twelve of the final fifteen events to act as crew chief while other drivers competed in the car.

[7] In early 2011, Keselowski declared his intention to compete for the 2011 NASCAR Sprint Cup Series Rookie Of The Year title; he was the only driver to do so as of the start of Speedweeks at Daytona International Speedway,[8] however Andy Lally stated his intention to run for the award while Speedweeks was underway.

[14] Shortly after Keselowski's surprise finish in the Duels, he received help from a number of sources, including tires from Evernham Motorsports and an engine from Penske Racing.

[18] In March 2011, Keselowski had severe abdominal pain and needed gallbladder surgery;[18] Dennis Setzer filled in for races at Bristol, where he finished 38th, and Martinsville, where the team withdrew after a practice crash.

29 Brad Keselowski Racing in the Camping World Truck Series at Talladega Superspeedway as a replacement driver for Austin Theriault, who had been injured earlier in the season.

[33] Later that year, he joined NASCAR Xfinity Series team MBM Motorsports to become Chad Finchum's crew chief.
