"Edelweiss" is a show tune from the 1959 Rodgers and Hammerstein musical The Sound of Music. It is named after the edelweiss, a white flower found high in the Alps. The song was created for the 1959 Broadway production of The Sound of Music, as a song for the character Captain Georg von Trapp. In the musical, Captain von Trapp and his family sing this song during the concert near the end of Act II. It is a statement of Austrian patriotism in the face of the pressure put upon him to join the navy of Nazi Germany following the Anschluss. It is also Captain von Trapp's subliminal goodbye to his beloved homeland, using the flower as a symbol of his loyalty to Austria. In the 1965 film adaptation, the song is also sung by the Captain earlier in the film when he rediscovers music with his children.

Rodgers and Hammerstein was a theater-writing team of composer Richard Rodgers (1902–1979) and lyricist-dramatist Oscar Hammerstein II (1895–1960), who together created a series of innovative and influential American musicals. Their musical theater writing partnership has been called the greatest of the 20th century.
