The track, believed to have been originally recorded for the pop legend's 1991 Dangerous album, was released on Jackson's official website at midnight and is now being played by radio stations worldwide.
'This Is It' features backing vocals from the late singer's brothers, but it is unclear whether these were included before or after his death, BBC News reports.
The song will feature on a forthcoming two-disc Jackson compilation album of the same name. Additionally, it will be played over the closing credits of Michael Jackson's This Is It, a new film documenting the star's rehearsals for a 50-date residency at London's O2 arena.
In a statement, Sony Music Entertainment described the premiere as "yet another exciting moment in music history for one of the world's most revered artists".
Jackson passed away in Los Angeles on June 25 after suffering a heart attack.
