"True Blue" is a song by American singer Madonna from her third studio album of the same name (1986), released as the third single on September 10, 1986, by Sire Records.
Written and produced by Madonna and Steve Bray, the song deals with Madonna's feelings for her then-husband Sean Penn. A dance-pop song, it features instrumentation from a rhythm guitar, a synthesizer, keyboards, and drums. The main chorus is backed by an alternate one, incorporating a chord progression generally found in doo-wop music.
Received by critics as a light-hearted and cute retro song, "True Blue" topped the charts in the United Kingdom, Ireland and Canada and became another consecutive top-ten song in United States for Madonna, by reaching number three on the Billboard Hot 100.
The original music video portrayed her again with a new look, leaner and sporting platinum blond bushy hair. An alternate video was made through the "Make My Video" contest on MTV. The final selected videos had a similar theme of a 1950s-inspired setting and the storyline following the lyrics of the song.
"True Blue" has been performed on the Who's That Girl World Tour (1987) and the Rebel Heart Tour (2015–2016).
