"Sweet 19 Blues" (stylized as "SWEET 19 BLUES") is a song recorded by Japanese recording artist Namie Amuro. The song was composed, written and arranged by Tetsuya Komuro for her same title debut album. A month after its release, her label Avex Trax released the song as a recut single due to popular demand. The song's subject and the album was about the melancholic passing of another sweet year of youth, which is a particularly Japanese obsession.

It did not achieve the success of her previous records but debut at No. 2 with over 100,000 copies sold in its first week and sold about 500,000 units, a great feat for a post-album single. The single was certified platinum by the RIAJ for 400,000 copies shipped to stores.

The song was later served as the ending theme song for the 1996 comedy That's Cunning! Shijo Saidai no Sakusen?, in which she also starred. Marked the first and only time she used a track to promote theatrically. Miliyah Kato's "19 Memories" later sampled the song.

The new version of the song marked 18 years since its original release in 2014.

The song carries its album's title, which according to Ted Mills from AllMusic, was a reflection of a "melancholic passing of another sweet year of youth" and a "particular Japanese obsession".

The song "Joy", which features vocals by M.C.A.T., is in fact a shortened version to what appears on the CD single of "Sweet 19 Blues"; two additional remixes appeared on it, whilst an original mix was featured on his single "Thunder Party". "Joy" was originally on m.c.A.T's fifth studio album Crossover.

The new version of the video was directed by Kanji Suto.
