Niccolò Jommelli (Italian: [nikko'l? jom'm?lli]; 10 September 1714 – 25 August 1774) was a Neapolitan composer.
He was born in Aversa and died in Naples.
Along with other composers mainly in the Holy Roman Empire and France, he was responsible for certain operatic reforms including reducing ornateness of style and the primacy of star singers somewhat.
