Little Toot is a 1939 children's picture book written and illustrated by Hardie Gramatky.

It features Little Toot, a small young tugboat in New York Harbor who does not want to tug.

In 2007, in honor of what would have been Gramatky's 100th birthday, Penguin Putnam publishers rescanned the original artwork, added nine original full-color sketches by the illustrator, and brought back detailed endpapers so the book has been restored to its first-edition colors and vibrancy.

In exile, Little Toot realizes that he must "grow up" - in other words, give up his careless ways - in order to earn respect from the other boats...including Big Toot, who has been stuck towing garbage scows ever since that incident with the ocean liner.

An animated adaptation of Little Toot and the Loch Ness Monster was featured in Shelley Duvall's Bedtime Stories with Rick Moranis as its narrator.
