The 2011 Dunlop MSA British Touring Car Championship was the 54th British Touring Car Championship (BTCC) season.
Cars conforming to the Next Generation Touring Car (NGTC) specification were allowed to compete in the championship for the first time, in a phased transition from Super 2000 specification to the NGTC specification. The season was also the final time that cars built to the BTC Touring specification were allowed to compete, ending the specification's decade of competition in the BTCC.
Team Dynamics' Matt Neal claimed his third BTCC title after finishing 8th in the final round of the season, two places ahead of team mate and rival Gordon Shedden, who was beaten to the title by eight points. Reigning Champion Jason Plato finished third after suffering a puncture in the first race of the final meeting at Silverstone. With the Hondas claiming a 1–2, this all but eliminated Plato from the title fight.
Joint fourth in the outright championship were Independents' title protagonists Mat Jackson and James Nash, with Jackson finishing fourth on merit of race wins, four to Nash's one. Nash, however, claimed the Independents' title in the first race at Silverstone after Jackson also suffered a puncture. Both however had torrid races after, failing to score points in both races. Nash's team, Triple 8 Race Engineering also claimed the Independents Teams' championship.
With Neal and Shedden first and second in the Drivers' championship, Honda easily clinched both the Teams' and Manufacturers' championships.
The entry list for the 2011 season was revealed at the championship's Media Day held at Silverstone on 24 March 2011.
All races were held in the United Kingdom. The calendar was announced by the championship organisers on 8 September 2010, with no major changes from 2010.
