1908–09 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.

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.

At the end of the season, the winners of the two sections played a match to decide the overall champions.
