The 2004–05 Football League Championship (known as the Coca-Cola Championship for sponsorship reasons) was the thirteenth season under its current league division format. It began in August 2004 and concluded in May 2005, with the promotion play-off finals. This was the first season to feature the rebranded Football League. The First Division, Second Division and Third Division were renamed the Football League Championship, Football League One and Football League Two respectively. Coca-Cola replaced the Nationwide Building Society as title sponsor.
