"I'm in the Mood for Love" is a popular song published in 1935. The music was written by Jimmy McHugh, with the lyrics by Dorothy Fields. The song was introduced by Frances Langford in the movie Every Night at Eight released that year.

It became Langford's signature song. Bob Hope, who frequently worked with Langford entertaining troops in World War II, later wrote that her performance of the song was often a show-stopper.

Wong Kar-wai's acclaimed 2000 romantic drama film In the Mood for Love borrows its English title from the song. Wong had planned to name the film Secrets until listening to the song late in post-production.^{[citation needed]}
