The Eton wall game is a game similar to football and rugby union, that originated from and is still played at Eton College. It is played on a strip of ground 5 metres wide and 110 metres long (The Furrow) next to a slightly curved brick wall (The Wall), erected in 1717.

The traditional and most important match of the year is played on St Andrew's Day, as the Collegers (King's Scholars) take on the Oppidans (the rest of the school). Although College has only 70 boys to pick from, compared to the 1250 or so Oppidans, the Collegers have one distinct advantage: access to the field on which the Wall Game is played is controlled by a Colleger.

Despite this, it is usual for them to allow the Oppidans to use it whenever they wish. On the annual St. Andrew's Day match, the Oppidans climb over the wall, after throwing their caps over in defiance of the Scholars, while the Collegers march down from the far end of College Field, arm-in-arm, towards the near end, where they meet the Oppidans.

The Wall Game is also played on Ascension Day, immediately after the early morning service on the roof of College Chapel. Various scratch matches are also played throughout the Michaelmas and Lent terms, where boys from different year groups, as well as masters, take part.
