The West Coast Eagles are a professional Australian rules football club based in the inner-Perth suburb of Lathlain, Western Australia. The club was founded in 1986 as one of two expansion teams in the Australian Football League (AFL), then known as the Victorian Football League, and has competed in the competition ever since. The West Australian Football Commission wholly owns the West Coast Eagles and the Fremantle Football Club, the AFL's other Western Australian team.
The West Coast Eagles are one of the most successful clubs in the AFL era (1990 onwards). They have won the second most premierships (four, second to Hawthorn) of any club in that time and were the first non-Victorian team to compete in and win an AFL Grand Final, achieving the latter feat in 1992. The Eagles have since won premierships in 1994, 2006 and 2018. They are one of the most profitable and influential clubs in the league, and as of 2021 have more members than any other club with over 106,000
