Korsvoll IL's supporter club was founded in 2005, and is named "Gladlaksene".

In 2010, Korsvoll won their Third Division group, but were defeated by Nesodden in the promotion-playoffs.

One of Korsvoll Fotball's most memorable moment came in the 2007 Norwegian Football Cup match against Stabæk.

But a late freekick goal and a stoppage time goal scored on a corner by Korsvoll's goalkeeper Stian Straume sent the game into extra time.

However Alanzinho scored three goals and Korsvoll lost the game 2-5 after extra time.
