Ismael "Esy" Morales (March 3, 1916 - November 2, 1950) was a Puerto Rican musician.

Before the age of ten, Esy was performing on tenor sax, clarinet and flute.

Morales went on to form his own band, The Esy Morales Orchestra and had a cameo appearance in the 1949 motion picture Criss Cross performing the song "Jungle Fantasy".

[2] The song Jungle Fantasy appears on Herbie Mann's 65th Birthday Celebration: Live At The Blue Note In New York City (Live), as well as Yusef Lateef's 1960 recording The Centaur and the Phoenix.

Morales died in 1950 at the age of 33 from a heart attack which was possibly brought on by diabetes.
