A Ballads (stylized as BALLADS) is the second greatest hits compilation 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". Released in six formats featuring a photograph by JFKK, A Ballads received favorable reviews from music critics. Many praised the collection for including some of Hamasaki's best vocal work, and commended the songwriting. Minor criticism was aimed on the newer renditions of the original songs. Commercially, the album was a success in Japan, reaching number one on the Oricon Albums Chart, making it Hamasaki's second compilation and eighth album to reach the top spot. It was certified Million by the Recording Industry Association of Japan (RIAJ) for shipments of one million units. The album experienced limited promotion during its release, with some of the tracks appearing during Japanese commercial endorsements.

During its promotion, Avex Trax and Hamasaki received over 100,000 messages from fans, telling them their opinions about the unfinished demo. Due to the mixed response of her fanbase, Hamasaki decided to develop the song further and release it as part of an upcoming compilation album, which was later named A Ballads. During the process, Hamasaki confessed that "[she] had never before written lyrics that were based on messages received directly from [her] fans. It was with "Rainbow" that [she] decided to give this approach a try". A Ballads is Hamasaki's first compilation to compile songs that were inspired by ballad music, with it portraying her second greatest hits album after A Best (2001).
