Rio Rita is a 1929 American pre-Code RKO musical comedy starring Bebe Daniels and John Boles along with the comedy team of Wheeler & Woolsey.. The film is based on the 1927 stage musical produced by Florenz Ziegfeld, which originally united Wheeler and Woolsey as a team and made them famous. The film was the biggest and most expensive RKO production of 1929 as well as the studio's biggest box office hit until King Kong (1933). Its finale was photographed in two-color Technicolor. Rio Rita was chosen as one of the 10 best films of 1929 by Film Daily.

RKO Radio Pictures Inc., commonly known as RKO Pictures or simply RKO, was an American film production and distribution company, one of the "Big Five" film studios of Hollywood's Golden Age. The business was formed after the Keith-Albee-Orpheum theater chain and Joseph P. Kennedy's Film Booking Offices of America studio were brought together under the control of the Radio Corporation of America (RCA) in October 1928. RCA executive David Sarnoff engineered the merger to create a market for the company's sound-on-film technology, RCA Photophone, and in early 1929 production began under the RKO name. Two years later, another Kennedy concern, the Pathé studio, was folded into the operation. By the mid-1940s, RKO was controlled by investor Floyd Odlum.
