The 2009–10 Football League (known as the Coca-Cola Football League for sponsorship reasons) was the 111th completed season of the Football League. It began in August 2009 and concluded in May 2010, with the promotion play-off finals. The Football League is contested through three Divisions. The divisions are the League Championship, League One and League Two. The winner and the runner up of the League Championship will be automatically promoted to the Premier League and they will be joined by the winner of the League Championship playoff. The bottom two teams in League Two will be relegated to the Conference Premier. The league was won by Newcastle United, with West Bromwich Albion as runners up. Both teams were promoted to the Premier League. Sheffield Wednesday, Plymouth Argyle and Peterborough United were relegated into League One. Grimsby Town and Darlington were relegated from the Football League.
