Stephen Storace (4 April 1762 – 19 March 1796) was an English composer. His sister was the famous opera singer Nancy Storace. He was born in London in the Parish of St Marylebone to an English mother and Italian father. Relatively little is known through direct records of his life, and most details are known second-hand through the memoirs of his contemporaries Michael Kelly, the actor John Bannister, and the oboist William Thomas Parke.
His father, Stefano Storace, an Italian contrabassist, taught him the violin so well that at ten years old he played successfully the most difficult music of the day. The composer's youth was spent entirely in the company of musicians, since his father (also a composer and arranger) was the Musical Director of Vauxhall Gardens. Mistrusting the quality of musical education available in England, Stefano Storace sent his son to Italy to study, at the Conservatorio di Sant' Onofrio, Naples. Stephen neglected his musical studies in Italy, and went on painting expeditions with Thomas Jones. His interest in art may not have been entirely extinguished, however - unlike the works of any of his English contemporaries, the printed vocal scores of all his operas feature elaborate engravings of what are presumed to be the stage-designs, and it is suggested that these drawings were Stephen's own work. No other artist, at least, seems to have claimed credit for them. Towards the end of their studies, Stephen and Nancy first made the acquaintance of Michael Kelly, whom they encountered by chance in Livorno. Kelly was with English-speaking friends, and ventured an opinion (in English) as to whether the young person with Stephen was a boy or a girl. "The person is a she-animal" retorted an offended Nancy in English as the first remark in what would be a lifelong friendship with both the Storaces.
