III – Tri-Logy is the third and final studio album from the Finnish group Kingston Wall. The album name is sometimes cited as Tri-Logy or Tri~Logy.

This album was originally released under the band's own record label, Trinity, in autumn 1994. It was also licensed and released in Japan by Japanese Zero record label. Both of these prints have been sold out in the 1990s and are considered somewhat collector's items. In the original print, the front cover featured a Kingston Wall logo as a sticker on the jewel case.

In 1998, Finnish record label Zen Garden (later SonyBMG Finland) re-released the whole Kingston Wall discography as remastered versions along with a 2-disc limited print-version of each album which included a Bonus CD featuring rare/unreleased studio and live material. These 2-disc versions have also been sold out and are considered collectibles. The album is still available as a remastered 1-disc version from Zen Garden (2006). To date, Tri-Logy is the only original Kingston Wall album available on iTunes in the United States.
