Birmingham Royal Ballet (BRB) is one of the five major ballet companies of the United Kingdom, alongside The Royal Ballet, the English National Ballet, Northern Ballet and Scottish Ballet. Founded as the Sadler's Wells Theatre Ballet, the company was established in 1946 as a sister company to the earlier Sadler's Wells company, which moved to the Royal Opera House that same year, subsequently becoming known as The Royal Ballet.

The Royal Ballet is a British internationally renowned classical ballet company, based at the Royal Opera House in Covent Garden, London, England. The largest of the five major ballet companies in Great Britain, the Royal Ballet was founded in 1931 by Dame Ninette de Valois. It became the resident ballet company of the Royal Opera House in 1946, and has purpose-built facilities within these premises. It was granted a royal charter in 1956, becoming recognised as Britain's flagship ballet company.
