John Wall Callcott (20 November 1766 – 15 May 1821) was an eminent English composer.
Callcott was born in Kensington, London. He was a pupil of Haydn, and is celebrated mainly for his glee compositions and catches. In the best known of his catches he ridiculed Sir John Hawkins' History of Music. Although ill-health prevented Callcott from completing his Musical Dictionary, His Musical Grammar (1806) remained in use throughout the 19th century.
