Fun! fun! fun! is a pop-punk album by Japanese pop punk band Shonen Knife, released on July 6, 2007 on Blues Interactions Japan. The album marked the 25th anniversary of the band.
A remastered version with all-English lyrics (catalog number BF-7CD) was on sale during the band's European tour in 2009. The cover art of the English version has a blue background in place of the Japanese version's green background, and is in a regular CD jewel case instead of the Japanese version's cardboard gate-fold case.
