Lech Browary Wielkopolski (Polish pronunciation: [ˈlɛɣ brɔˌvarɨ vjɛlkɔˈpɔlskʲi];[1] English: Lech Breweries of Greater Poland) is a big industrial brewery in Poznań, with a production capacity of 7.5 million hl.

The plant is owned by Asahi Breweries subsidiary Kompania Piwowarska SA.

As a result of the tender a majority shareholder in the company was Euro Agro Centrum Poznań, owned by entrepreneur Jan Kulczyk.

Three years later, the two breweries were combined to form Kompania Piwowarska.

On 11 March 2007, at the newly opened section of the brewery, the world's biggest beer mug was erected and filled with Lech Pils beer, setting a Guinness world record for the largest number of people drinking from one mug, which included 4250 liters of beer.
