The Best Children’s Books About Fish

By the Bookroo Editors
Updated July 24, 2026

A fish is usually the first wild animal a child gets to stare at up close — through the glass of a pet-store tank, over the rail of a dock, or in a tide pool where something silver flickers off before anyone can name it. Fish do not bark, fetch, or make faces, which is exactly why picture books have spent seventy years handing them one: a pout, a stolen hat, a coat of scales worth arguing over. They are also the animal children ask the hardest questions about. Do they sleep. Do they feel it. How far down does it actually go.

Bookroo’s collection of 587 books about fish runs from bathtub board books to deep-sea nonfiction, and our editors chose ten that reward a second reading. You will find the read-aloud classics most parents half-remember, two nonfiction titles for the child who wants facts rather than morals, and a chapter book for the reader who has outgrown the picture-book shelf. Start with the shortlist, then browse by age — board books for toddlers, picture books for the three-to-eight crowd, and longer fish stories for eight and up.
