Nélida Roca (Spanish pronunciation: [ˈneliða ˈroka]; May 30, 1929 – December 4, 1999), was one of the first showbusiness divas and sex symbols of Argentina.

Born Nélida Mercedes Musso in Buenos Aires, her friends and colleagues fondly called her La Roca ("The Rock").

Nélida married Julio Rivera Roca, a jazz piano player, in 1949, which got her to complete her dream as the lead vocalist in his orchestra.

The show's commercial success allowed Amadori to triple the price of the seats, and she became a legend in her genre during the 1950s.

Critics and her public came to know her as "The Venus of Corrientes Avenue" (the Buenos Aires theatre district).
