Brouwerij 't IJ is a small brewery in Amsterdam, Netherlands. It is located in a former bath house named Funen, next to the De Gooyer windmill. The brewery was opened by Kaspar Peterson, a former musician, in October 1985 and was one of several small breweries that opened in cities around the Netherlands in response to consumers' dissatisfaction with beer brewed by the larger companies. It brews twelve standard beers and three seasonal beers, besides limited edition beers. The brewery allows tours and tastings, and has a pub with an outdoor terrace. It opens from 2 p.m. until 8 p.m. but no later, owing to local residents' objections to the noise. It brews in the pub basement and in a building in the nearby Zeeburgerpad. In 2019 it opened a second bar in the Blauwe Theehuis in the Vondelpark. The brewery's logo features an ostrich, with an egg, and a distant windmill. The brewery is named after the nearby IJ waterbody.
