The Apollo Theatre is a Grade II listed West End theatre in Shaftesbury Avenue in the City of Westminster, in central London. Designed by the architect Lewin Sharp for owner Henry Lowenfeld, it became the fourth legitimate theatre to be constructed on the street when it opened its doors on 21 February 1901, with the American musical comedy The Belle of Bohemia.

Henry Lowenfeld in Polish, Henryk Loewenfeld, was a Polish-born British entrepreneur and theatrical impresario. He founded the Kops Brewery, the UK's first UK brewer of non-alcoholic beer, and built London's Apollo Theatre and the Ocean Hotel in Sandown on the Isle of Wight.
