The Showdown is an Australian rules football game played by the two Australian Football League (AFL) teams from South Australia, the Adelaide and Port Adelaide football clubs. The first AFL premiership fixture between the two clubs took place on 20 April 1997. The South Australian Brewing Company, makers of West End beers, were the first sponsors of the game and decided that the "Showdown" would be an appropriate name as a promotional opportunity for games between these two clubs, since it was the first time two South Australian teams had played against each other in the AFL.
