"Borderline" is a song by American singer Madonna from her debut self-titled studio album (1983), written and produced by Reggie Lucas. In 1982, Madonna was signed on by Sire Records for the release of two 12-inch singles; after the success of first single "Everybody", the label approved the recording of an album, and the singer decided to work with Lucas. "Borderline" is a pop song with post-disco elements whose sounds recall the music of the 1970s, while the lyrics find a woman complaining of her lover's chauvinism.

Madonna is the eponymous debut studio album by American singer Madonna, released on July 27, 1983, by Sire Records. In the late 1970s, Madonna had established herself as a singer in downtown New York City; alongside her Michigan boyfriend Stephen Bray, she put together a demo tape with four dance tracks and began pitching it around local nightclubs. She managed to get Mark Kamins, the resident DJ at Danceteria, to play "Everybody" —one of the songs from the tape. The song was met with a positive reception from the crowd, and Kamins took Madonna to Sire Records, where label president Seymour Stein signed her on for three twelve-inch singles. Following its release on October 2, 1982, "Everybody" found success on the dance scene, and the label approved the recording of an album.
