The Theatre Royal, Drury Lane, commonly known as Drury Lane, is a West End theatre and Grade I listed building in Covent Garden, London, England. The building faces Catherine Street and backs onto Drury Lane. The present building, opened in 1812, is the most recent of four theatres that stood at the location since 1663, making it the oldest theatre site in London still in use. According to the author Peter Thomson, for its first two centuries, Drury Lane could "reasonably have claimed to be London's leading theatre". For most of that time, it was one of a handful of patent theatres, granted monopoly rights to the production of "legitimate" drama in London.

West End theatre is mainstream professional theatre staged in the large theatres in and near the West End of London. Along with New York City's Broadway theatre, West End theatre represents the highest level of commercial theatre in the English-speaking world. Seeing a West End show is a common tourist activity in London. Famous screen actors, British and international alike, frequently appear on the London stage.
