Grimbergen is the brand name of a variety of Belgian abbey beers. Originally made by Norbertine monks in the Belgian town of Grimbergen, it is now brewed by different breweries in Belgium, France, Poland and Italy.

Beer in Belgium includes pale ales, lambics, Flemish red ales, sour brown ales, strong ales and stouts. In 2018, there were 304 breweries in Belgium, including international companies, such as AB InBev, and traditional breweries, such as Trappist monasteries. On average, Belgians drink 68 litres of beer each year, down from around 200 each year in 1900. Most beers are bought or served in bottles, rather than cans, and almost every beer has its own branded, sometimes uniquely shaped, glass. In 2016, UNESCO inscribed Belgian beer culture on their list of the intangible cultural heritage of humanity.
