Greatest Hits is a double-disc greatest hits album for late rapper 2Pac, released by Amaru/Death Row/Jive/Interscope Records in 1998. The album's non-chronological sequence highlights 2Pac's career; the 21 popular hits, some slightly re-edited for legal reasons, are accompanied by four previously unreleased songs: the dead friends tribute "God Bless the Dead", the dedication song "Unconditional Love", the tough talk "Troublesome '96", and the album's single "Changes" also helped earn 2Pac the first and only posthumous Grammy Award nomination since for Best Rap Solo Performance. Some tracks have alternate mixes, while "California Love" makes its first proper album appearance after only being available as a single prior.
