The 2015 Dunlop MSA British Touring Car Championship (commonly abbreviated as BTCC) was a motor racing championship for production-based touring cars held across England and Scotland. The championship featured a mix of professional racing teams and privately funded amateur drivers competing in highly modified versions of family cars, which are sold to the public and meet the championship's technical regulations. The 2015 season was the 58th British Touring Car Championship season and the fifth season for cars conforming to the Next Generation Touring Car (NGTC) specification.

Colin Turkington was the defending drivers' champion. West Surrey Racing was the defending teams' champion, and MG the defending manufacturers' champions.
