Melesio Morales (sometimes spelled Melisio Morales) (December 4, 1838 – May 12, 1908) was a Mexican composer.
Morales was born and died in Mexico City, where he studied music; two of his operas, written in Italian, were performed there. He lived in Europe from 1865 to 1868, and his success in Florence with the opera Ildegonda in 1866 made him a star in his native country. He composed, conducted, and taught in Mexico City until his death. His works include ten operas, two cantatas, and orchestral and choral works.
