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.
