1890 WAFA season

The 1890 WAFA season was the 6th season of senior Australian rules football in Perth, Western Australia. The Unions Football Club changed its name to "Fremantle Football Club" in April 1890 to better represent the locality in which they were based. They also won their fourth premiership of a four-peat this season.
