Siren of Atlantis, also known as Atlantis the Lost Continent, is a 1949 American black-and-white fantasy-adventure film, distributed by United Artists, that stars Maria Montez and her husband Jean Pierre Aumont. It was the first feature she made after leaving Universal Pictures.

María África Gracia Vidal, known professionally as Maria Montez, was a Dominican actress who gained fame and popularity in the 1940s starring in a series of filmed-in-Technicolor costume adventure films. Her screen image was that of a seductress, dressed in fanciful costumes and sparkling jewels. She became so identified with these adventure epics that she became known as The Queen of Technicolor. Over her career, Montez appeared in 26 films, 21 of which were made in North America, with the last five being made in Europe.
