Bass is the name of a former brewery and the brand name for several English beers brewed in Burton upon Trent. Bass is most particularly associated with their pale ale. The distinctive Red Triangle logo for Bass Pale Ale was Britain's first registered trademark.

By the end of the 20th century, following decades of closures and consolidation, Bass was left with one of the two large breweries remaining in the town. It also had substantial holdings in hotels, now owned by InterContinental Hotels Group (IHG).

Over the years of its ascendancy, Bass maintained its dominance in the UK market by the acquisition of other brewers such as Mitchells & Butlers (1961), Charringtons (1967) and William Stones Ltd (1968) (with the overall company being known as Bass, Mitchells and Butlers or Bass Charrington at various times).
