Port Adelaide Football Club is a professional Australian rules football club based in Alberton, South Australia. The club's senior men's team plays in the Australian Football League (AFL), where they are nicknamed the Power, whilst its reserves men's team competes in the South Australian National Football League (SANFL), where they are nicknamed the Magpies. Since its founding, the club has won an unequalled 36 SANFL premierships and 4 Championship of Australia titles, in addition to an AFL Premiership in 2004. It has also fielded a women's team in the AFL Women's (AFLW) league since 2022. Founded in 1870, Port Adelaide is the oldest professional football club in South Australia and the fifth-oldest club in the AFL. Port Adelaide was a founding member of the South Australian Football Association (SAFA), later renamed as the SANFL. Port Adelaide has repeatedly asserted itself as a dominant force within South Australian football, going undefeated in all competitions in 1914, and enjoying sustained periods of success under coaches Fos Williams and John Cahill, sharing a combined 19 premierships between them. After entering the AFL in 1997, the club claimed three minor premierships and a premiership under coach Mark Williams between 2002 and 2004.
