Gaetano Coronaro (18 December 1852 – 5 April 1908) was an Italian conductor, pedagogue, and composer. He was born in Vicenza and had his initial musical training there followed by study from 1871 to 1873 at the Milan Conservatory under Franco Faccio. He composed orchestral works, sacred music and chamber pieces as well as five operas. La Creola which premiered at the Teatro Comunale di Bologna in 1878 was the only one to have any success.
Coronaro had settled in Milan by 1876 where he conducted at La Scala and taught at the Milan Conservatory. In 1894 he was made professor of composition there. Amongst his students was the composer Arrigo Pedrollo. Coronaro died in Milan at the age of 55. His brothers, Antonio (1851–1933) and Gellio Coronaro (1863–1916) were opera composers as well. Antonio was also the organist at the Cathedral of Vicenza from 1885 until his death.
