Brawn GP Formula One Team, the trading name of Brawn GP Limited, was a Formula One motor racing team and constructor, created by a management buyout of Honda Racing F1 Team. It only competed in the 2009 Formula One World Championship, with drivers Jenson Button and Rubens Barrichello. The team clinched that year's constructors' championship, and Button took the drivers' title. For 2010, the team again changed identity, becoming Mercedes GP.

On its racing debut, the season-opening 2009 Australian Grand Prix, the team took pole position and 2nd place in qualifying and went on to finish first and second in the race. Button won six of the first seven races of the season and on 18 October at the Brazilian Grand Prix, he secured the 2009 Drivers' Championship and the team won the Constructors' Championship. Barrichello won twice and finished third in the Drivers' Championship. The team won eight of the season's seventeen races, and by winning both titles in its only year of competition became the first to achieve a 100% championship success rate.

Jenson Alexander Lyons Button MBE (born 19 January 1980) is a British Formula One driver currently signed to McLaren. He was the 2009 World Drivers' Champion for Brawn GP.

Button began karting at the age of eight and achieved early success, before progressing to car racing in the British Formula Ford Championship and the British Formula Three Championship. He first drove in Formula One with the Williams team for the 2000 season. The following year he switched to Benetton, which in 2002 became Renault, and then for the 2003 season he moved to BAR. They were subsequently renamed Honda for the 2006 season, during which Button won his first Grand Prix in Hungary, after 113 races.

Following the withdrawal of Honda from the sport in December 2008, he was left without a drive for the 2009 season, until Ross Brawn led a management buyout of the team in February 2009, and Button suddenly found himself in a highly competitive, Mercedes-engined car. He went on to win a record-equalling six of the first seven races of the 2009 season, securing the World Drivers' Championship at the Brazilian Grand Prix, having led on points all season; his success also helped Brawn GP to secure the World Constructors' Championship. For 2010, he moved to McLaren, partnering fellow British racer and former World Champion Lewis Hamilton. After finishing fifth for the team in 2010, Button finished the 2011 season as runner-up.

Schumacher's retirement at the end of 2006 made Barrichello the most experienced driver on the grid, and at the 2008 Turkish Grand Prix he became the most experienced driver in F1 history. He became the first driver to reach 300 Grand Prix entries and 300 starts, doing so in 2010. He was also appointed chairman of the Grand Prix Drivers' Association in 2010, but after losing his seat in Formula One, he was replaced by Pedro de la Rosa.
