El Morocco, sometimes nicknamed Elmo or Elmer, was a 20th-century nightclub in the Manhattan borough of New York City.

In 1931, John Perona (born Enrione Giovanni Perona in Chiaverano in the Province of Turin, Italy),[1] an Italian immigrant, with Martín de Alzaga[2][3] opened El Morocco as a speakeasy at 154 East 54th Street, on the south side of 54th Street in the middle of the block between Lexington Avenue and Third Avenue, where the Citigroup Center now stands.

[5] Before taking over the El Morocco, Uchitel owned the Eden Roc Hotel in Miami Beach for several years.

The article talks about the opera opening the night before, and all of the parties that the attendees went to afterwards, including at 21 Club and El Morocco.

The 1955 film My Sister Eileen includes the club, starring Janet Leigh and Jack Lemmon.
