"Happy Talk" is a show tune from the 1949 Rodgers and Hammerstein musical South Pacific. It is sung by Bloody Mary to the American lieutenant Joe Cable, about having a happy life, after he begins romancing her daughter Liat. Liat performs the song with hand gestures as Mary sings.

South Pacific is a musical composed by Richard Rodgers, with lyrics by Oscar Hammerstein II and book by Hammerstein and Joshua Logan. The work premiered in 1949 on Broadway and was an immediate hit, running for 1,925 performances. The plot is based on James A. Michener's Pulitzer Prize–winning 1947 book Tales of the South Pacific and combines elements of several of those stories. Rodgers and Hammerstein believed they could write a musical based on Michener's work that would be financially successful and, at the same time, send a strong progressive message on racism.
