1908–09 Western Football League

The 1908–09 season was the 17th in the history of the Western Football League.

For the last time, Division One was split into two sections of six clubs, reorganised from the previous season, with the winner of each section playing each other in a Championship decider. Brighton & Hove Albion won Section A and reigning champions Millwall won Section B, with Millwall winning the decider 2–1 in a replay after the first match was drawn. At the end of this season, all 14 clubs in Division One resigned from the League, leaving Division Two as the only division in the league. All the member clubs of Division One also competed in the Southern League during this season. As with the previous season, the Division Two champions were Bristol City Reserves.
