The Sunday Football League Western Australia (SFL WA), commonly known as the Sunday Football League (SFL), is a defunct semi-professional Australian rules football league that was based in the southern suburbs of Perth, Western Australia, Australia. The Kenwick Football Club are the most successful club in the history with 9 senior team premierships.
The league began in 1984 after a name change from the South Suburban Murray Football League and was headquartered in Perth's south eastern suburbs, for a period at Lathlain Park – the home ground of the Perth Football Club. It was notable as Perth's most popular Sunday competition, and each weekend up to 5,000 spectators attended the round of SFL matches.
In February 2009 it was announced that the league would not be operating for the 2009 football season with clubs applying to join the Western Australian Amateur Football League and the Peel Football League.
Armadale were admitted to the Peel Football League and the remaining clubs were admitted to the amateur league.
