Port Adelaide Football Club

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 it is nicknamed the Power, while its reserves men's team competes in the South Australian National Football League (SANFL), where it is nicknamed the Magpies. Since its founding, the club has won an unequalled 36 SANFL premierships and four Championship of Australia titles, in addition to an AFL Premiership in 2004. It has fielded a women's team in the AFL Women's (AFLW) competition since 2022 (S7).

Founded in 1870, Port Adelaide is the oldest professional football club in South Australia and was a founding member of the South Australian Football Association, later renamed 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. The club's sustained success in the SANFL eventually led it being granted a licence to compete in the AFL from 1997, becoming the second South Australian based side in the competition after the Adelaide Football Club in 1991. It its time in the AFL, the club has claimed four minor premierships and one premiership. Port Adelaide holds a unique status among AFL clubs, being the only pre-existing non-Victorian club to have entered the AFL from another league. It has an intense rivalry with intra-city opponents Adelaide; the two compete in twice-yearly fixture known as the Showdown, while historically it enjoyed a long-standing rivalry with fellow SANFL club Norwood. It has played home games in the SANFL, at both senior and reserves level, at its club headquarters of Alberton Oval, since 1880, and the venue is also used for home games in the AFLW and occasional pre-season fixtures in the AFL. In the national competition the club has played home games at Adelaide Oval since the venue's redevelopment concluded in 2014.

Port Adelaide first adopted the colours of black and white in 1902, in a design commonly known as the 'prison bars' guernsey, which the club wears to this day in the SANFL and in home showdown fixtures. Upon entering the AFL in 1997, the colours of teal and silver were added to the club palette and the Power nickname was adopted, to enable differentiation from the Collingwood Football Club, who wear black and white stripes and are nicknamed the Magpies.
