Lionel "Lal" Brough was a British actor and comedian. After beginning a journalistic career and performing as an amateur, he became a professional actor, performing mostly in Liverpool during the mid-1860s. He established his career in London as a member of the company at the new Queen's Theatre, Long Acre, in 1867, and he soon became known for his roles in Shakespeare, contemporary comedies, and classics, especially as Tony Lumpkin in She Stoops to Conquer.

The Queen's Theatre was a London theatre established in 1867 on the site of St Martin's Hall, a large concert room that had opened in 1850. It stood on the corner of Long Acre and Endell Street, with entrances in Wilson Street and Long Acre. The site is within the modern Camden, part of Covent Garden.
