Thwaites Brewery is a regional brewery founded in 1807 by Daniel Thwaites in Blackburn, Lancashire, England, and now located near Mellor in the Ribble Valley. Part of the company's beer business was sold to Marston's in March 2015, and the original brewery facility was demolished in 2019. Today, Thwaites still produces beer, but in much smaller quantities. The company has over 270 pubs, mainly in the North of England but reaching from the North Lakes area down to Solihull & Leicestershire.
