Jupiler (French: [ʒypilɛʁ], Flemish: [ˈʑypilɛr] or [ʑypiˈleː]) is a Belgian beer introduced in 1966, now brewed by Anheuser–Busch InBev at Piedboeuf Brewery in the Jupille-sur-Meuse neighbourhood of Liège.

Jupiler is the highest selling beer in Belgium, with around 40 percent share by volume.

They also sponsor the Belgium national football team and have sold special beer cans featuring photographs of the players.

Its slogan is "Men know why" (Dutch: "Mannen weten waarom"; French: "Les Hommes savent pourquoi").

On 20 February 2018, AB InBev announced that the brand name "Jupiler" will be replaced for a period of 5 months by "Belgium", in support of the Belgian team during the 2018 FIFA World Cup.
