Michael Kelly (25 December 1762 – 9 October 1826) was an Irish singer (tenor), composer and theatrical manager who made an international career of importance in musical history.
One of the leading figures in British musical theatre around the turn of the nineteenth century, and a close associate of Richard Sheridan's, he had been a friend of Mozart and Paisiello, and created roles in operas of both.
With his friend Nancy Storace, he was one of the first singers in that age from Britain and Ireland to make a front-rank reputation in Italy and Austria.
In Italy he was also known as O'Kelly or even Signor Ochelli.
Although the primary source for his life is his Reminiscences, it has been said 'Any statement of Kelly's is immediately suspect.'
