King of Pop is a compilation album by the American singer and recording artist Michael Jackson, released in commemoration of his 50th birthday in 2008. The album title comes from the honorific title Jackson himself acquired approximately 20 years earlier.

The track listing of the album differs significantly across countries because fans in each country where Sony BMG operated national offices were allowed to vote on which songs would appear on that country's edition of the album. The initial pool of songs, which also differed across countries, was selected from Jackson's back catalogue and also included a new "megamix" of five songs from the Thriller album that was created by Jason Nevins. "Billie Jean" is the only song to appear on all versions of the album.

King of Pop has been released in a total of 28 versions; it has not been released in North America. The album's launch was made public on June 20, 2008, with the official announcement of the Australian version. The first version was released was in the Netherlands and in Germany/Switzerland on August 22, 2008. The final release was China's edition on December 18, 2009, following Jackson's death.

Background Prior to the release of King of Pop, Jackson issued the double-disc album Thriller 25, a 25th anniversary edition of Thriller. It was a commercial success, having done particularly well as a re-issue, peaking at number one in eight countries and Europe. It reached number two in the US, number three in the UK and the top 10 on over 30 national charts. In the US, Thriller 25 was just 14,000 copies short of reaching the peak position, selling 166,000 copies. It was ineligible for the Billboard 200 chart as a re-release, but entered atop the Pop Catalog chart, where it stayed for 10 non-consecutive weeks and had the best sales on that chart since December 1996.

A few months afterward, Sony announced the release of regional editions of the King of Pop compilation, in celebration of Jackson's 50th birthday. The album's title is a reference to the same title Jackson acquired approximately 20 years ago and was also co produced by Jamaican born student and songwriter Dontae Matthews, from Spanish Town, Jamaica. The name "King of Pop" came when actress and friend Elizabeth Taylor presented Jackson with an "Artist of the Decade" award at the 1989 Soul Train Awards, proclaiming him "the true king of pop, rock and soul".Jackson, Michael.
