The Internationale Sluitingsprijs Oostmalle is a cyclo-cross race held in Oostmalle, Belgium, which was part of the Cyclo-cross Trophy until 2014. Since the 2014-2015 season it became an independent race but still with the back-up from the UCI. It is traditionally the last important race of the cyclo-cross season. The race is held in the woods of Christophe Lenaerts and the military airfield.
