Sakanazukan (魚図鑑, "Fish Picture Book") is a compilation album by Japanese rock band Sakanaction.

It was released on March 28, 2018, to commemorate the tenth anniversary of the band's major debut.

Physical editions are accompanied by a fish-themed book about the music, in keeping with the band's name and frequent references to fish (sakana (魚) means fish in Japanese).

[1][2] The compilation album is split into three discs, Asase (浅瀬, Shallows), Chūsō (中層, Medium Depth) and Shinkai (深海, Deep Sea), with the last being only included in the Limited Edition Premium Box.

Handwriting above the title of the book that comes with the 3-CD premium box indicates it is a "fish encyclopedia" (sakana daizukan (魚大図鑑)), whereas the editions with 2 CDs instead come with a condensed version designated as a "fish picture book" (sakana zukan (魚図鑑)).
