2003 British Rally Championship

The 2003 British Rally Championship season was the 45th season of the British Rally Championship. The season consisted of seven rounds — the Rally of Wales, scheduled for 22–23 March, was cancelled — and began on 25 April, with the Pirelli International Rally in the north east of England. The season ended on 26 October, at the Tempest South of England Rally. The series was organised by the Royal Scottish Automobile Club.
The title was won by Englishman Jonny Milner and Welsh co-driver Nicky Beech, driving a Toyota Corolla WRC.
