Amazon MP3 is an online music store owned and operated by Amazon.com. Launched in public beta on September 25, 2007, in January 2008 it became the first music store to sell music without digital rights management (DRM) from the four major music labels (EMI, Universal, Warner Music, and Sony BMG), as well as many independents. All tracks were originally sold in 256 kilobits-per-second variable bitrate MP3 format without per-customer watermarking or DRM; however some tracks are now watermarked. Licensing agreements with recording companies restrict the countries in which music can be sold: Amazon.com only sells music to US customers while Amazon.co.uk only sells music to UK customers.

After the United States, Amazon MP3 was launched in the United Kingdom on December 3, 2008, in Germany on April 1, 2009, and in France on June 10, 2009. The German edition has been available in Austria and Switzerland since December 3, 2009.

Amazon launched Amazon Cloud Player as an extension to Amazon MP3 store in the United States on March 29, 2011.
