Harpoon Brewery is an employee-owned American brewery, with locations in Boston, Massachusetts, and Windsor, Vermont.
Founded in 1986, the brewery was the first company to obtain a permit to manufacture and sell alcohol in the Commonwealth of Massachusetts in more than 25 years. In 2000, it purchased the former Catamount Brewery plant in Windsor. As of 2013, it was the twelfth-largest craft brewery and 19th-largest overall brewery in the United States.
The brewery is best known for its Harpoon India Pale Ale. It brews multiple other year-round beers including the award-winning Dark, UFO Hefeweizen, UFO Raspberry Hefeweizen, UFO White, and Boston Irish Stout. It also brews several house beers at Boston bars, including "Sevens Ale" for The Seven's Ale House in Beacon Hill.
