The Great Northern Brewery, on the Carrick Road, Dundalk, County Louth, was an Irish brewery. It was home to Harp Lager, and was formerly owned by Diageo. In 2015 the brewery closed, and production of Harp Lager and other products was moved to St. James's Gate Brewery in Dublin. The site has since been bought by John Teeling, and converted for operation as a distillery, the Great Northern Distillery.
