"Say Say Say" is a song by Paul McCartney and Michael Jackson. The track was written by the duo and produced by George Martin for McCartney's fifth solo album, Pipes of Peace (1983). The song was the pair's second duet after "The Girl Is Mine" from Jackson's Thriller (1982). It had been recorded a year before "The Girl Is Mine", at the same time as McCartney's 1982 Tug of War album. Upon its release in October 1983, "Say Say Say" became Jackson's seventh top ten hit in a year. It was a number one hit in the United States and reached number two in the United Kingdom. Also number one in Norway and Sweden, the single peaked within the top ten in Australia, Austria, New Zealand, the Netherlands and Switzerland.

Certified platinum by the Recording Industry Association of America, the song was promoted with a music video directed by Bob Giraldi. The video, filmed in Santa Ynez Valley, California, featured cameo appearances by Linda McCartney and La Toya Jackson. The short film centers around two con artists, "Mac and Jack", and is credited for the introduction of dialogue and storyline to music videos. After its debut, the video was considered too violent for broadcast by the National Coalition on Television Violence.
