A Ballads is the second greatest hits album by Japanese recording artist Ayumi Hamasaki. It was released physically on March 12, 2003, through Avex Trax, and digitally distributed worldwide on September 14, 2006, by Avex Entertainment Inc. It is her first compilation release in two years since A Best; it premiered three months after her sixth studio album Rainbow. The compilation compiles ballad-inspired singles released by Hamasaki between 1998 and 2003, while the material is divided into new-arrangement remixes and the original versions. With all the tracks written by Hamasaki, it includes two new songs—"Rainbow", which served as the album's promotional single, and a cover version of Japanese singer Yumi Matsutoya's 1975 track "Sotsugyō Shashin".
