Lionel John Alexander Monckton (18 December 1861 – 15 February 1924) was an English writer and composer of musical theatre. He was Britain's most popular musical theatre composer of the early years of the 20th century.

Monckton was born in London, the eldest son of the Town Clerk of London, Sir John Braddick Monckton, and Lady Monckton, the former Maria Louisa Long (1837–1920), an "enthusiastic amateur actress". His sister was Mrs Augusta Moore, who wrote popular novels as Martin J. Pritchard.

He was educated at Charterhouse School and Oriel College at Oxford University, graduating in 1885. There he acted in college theatrical productions and composed music for productions of the Oxford University Dramatic Society, of which he was a founder, and the Phil-Thespian Club. He initially joined the legal profession at Lincoln's Inn and began to practise law, but gained part-time work as a song writer and a theatre and music critic, first for the Pall Mall Gazette and later for the Daily Telegraph. His first theatre work was Mummies and Marriage, an operetta produced by amateurs in 1888. At the age of 29, in 1891, he finally managed to place the song "What will you have to Drink?", with lyrics by Basil Hood, in a professional musical burlesque called Cinder Ellen up too Late. After this, his songs were included in several other London shows.
