The sporting rivalry between Australian rules football clubs Carlton and Collingwood is the biggest and longest-lasting rivalry in the Australian Football League (AFL). The clubs not having met in a final since 1988, the rivalry is regarded by some as being among the most historic and significant in Australian sport. The Peter MacCallum Cup is the longest-running charity match in VFL/AFL history, with the first clash taking place in 1993. Occurring whenever the two sides meet for a Collingwood home game, the clash aims to raise awareness and funds for Melbourne's Peter MacCallum Cancer Centre.
