Grolsch Brewery is a Dutch brewery founded in 1615 by Willem Neerfeldt in Groenlo. In 1895 the de Groen family bought the brewery. They had started their own brewery in Enschede the Netherlands in the early 19th century. It held a significant stake until November 2007. Today the main brewery is located in Enschede.

It was awarded the Koninklijk (Royal) title in 1995. The Grolsch brand became a part of the SABMiller group in March 2008.

As part of the agreements made with regulators before Anheuser-Busch InBev was allowed to acquire SABMiller, the company sold Grolsch to Asahi Breweries in late 2016. The deal was expected to close during the first half of 2017.
