McElligot's Pool is a children's book written and illustrated by Theodor Geisel under the pen name Dr. Seuss and published by Random House in 1947.

Geisel painted some of the water colors that illustrate McElligot's Pool while vacationing with his wife, Helen, at the summer home of their friend Kelvin Vanderlip, in Southern California.

King of the Chicago Sun emphasized the book's humor: "This time prepare to chuckle under water for you'll be meeting the weirdest, wildest, funniest creatures of the sea which imagination can conjur".

[3] On March 2, 2021, Dr. Seuss Enterprises withdrew McElligot's Pool and five other books from publication because they "portray people in ways that are hurtful and wrong".

The book uses the word "Eskimo" in one instance, as an adjective describing a type of imagined fish that might swim from the North Pole to McElligot's Pool.
