Rivalries in the Australian Football League exist between many teams, most of which typically draw large crowds and interest regardless of both teams' positions on the ladder. The AFL encourages the building of such rivalries, as a method of increasing publicity for the league, to the point of designating one round each year as "Rivalry Round" when many of these match-ups are held on the one weekend. Whilst some rivalries, such as between teams from adjacent areas, are still strong, the designation of an entire round of fixtures as a Rivalry Round is often criticised due to some arbitrary match-ups, or ignoring stronger and more recent rivalries.

The Line in the Sand Match is the unofficial title given to the round 11, 2004, match between Australian Football League (AFL) clubs Hawthorn and Essendon, which was played at the Melbourne Cricket Ground on Saturday, 5 June 2004.
