"The Girl Is Mine" is a song recorded by American singer-songwriter Michael Jackson and English singer and musician Paul McCartney. The track was written and co-produced by Jackson and produced by Quincy Jones. It was released as the first single for Jackson's sixth solo album, Thriller (1982). The song was recorded at Westlake Studios, Los Angeles, from April 14 to 16, 1982. The year before, Jackson and McCartney had recorded "Say Say Say" and "The Man" for the latter's fifth solo album, Pipes of Peace (1983). Although "The Girl Is Mine" was released as a single, Jackson and McCartney never performed the song live.

Thriller is the sixth studio album by the American singer and songwriter Michael Jackson, released on November 29, 1982, by Epic Records. It was produced by Quincy Jones, who had previously worked with Jackson on his 1979 album Off the Wall and who would later produce his 1987 album Bad. Jackson wanted to create an album where "every song was a killer". With the ongoing backlash against disco music at the time, he moved in a new musical direction, resulting in a mix of pop, post-disco, rock, funk, synth-pop, and R&B sounds. Thriller foreshadows the contradictory themes of Jackson's personal life, as he began using a motif of paranoia and darker themes. Paul McCartney appears on "The Girl Is Mine", the first credited appearance of a featured artist on a Michael Jackson album. Recording took place from April to November 1982 at Westlake Recording Studios in Los Angeles, California, with a budget of $750,000.
