Nina Quartero (born Gladys Quartararo;[1] March 17, 1908 – November 23, 1985) was an American movie actress whose career spanned from 1928 to 1943.

Playing "Conchita," she is a source of strife in Wayne's relationship to the characters depicted by Laura La Plante and June Clyde.

Her final screen performances show Quartero playing very small parts, such as an uncredited native dancer in Green Hell (1940), and a bar-girl in A Lady Takes a Chance (1943).

Quartero once tried a publicity stunt by claiming that she was betrothed to Notre Dame All-American quarterback Frank Carideo.

Carideo demanded a retraction of Quartero's engagement announcement, although he admitted he knew her from a time when each resided in Mount Vernon, New York.
