Greatest Hits (Mariah Carey album)

Greatest Hits is the second greatest hits album by American singer-songwriter Mariah Carey, released on December 4, 2001, by Columbia Records. Released after her departure from Columbia, the album includes most of Carey's singles from 1990 to 2000, spanning her tenure at the label. It features her then fifteen US number-one singles, along with the UK number-one hits "Without You" and "Against All Odds".

In response to criticism from both reviewers and Carey herself of her first greatest hits album, #1's (1998), which focused on her US number-one singles, Greatest Hits was developed as a double album comprising a wider selection of Carey's work, including two additional number-one songs released after #1's. The album peaked at number fifty-two on the US Billboard 200 and number seven on the UK Albums Chart, and achieved platinum certifications in various countries, including double-platinum in the US and triple-platinum in the UK and Australia.

The album was re-released internationally as The Essential Mariah Carey on January 10, 2011, as part of Legacy Recordings's Essential series, featuring the same track listing. The US edition, released on April 24, 2012, featured extended mix versions and additional non-single tracks, personally selected by Carey.
