A new Dr. Seuss book is coming in 2026, nearly 35 years after the death of the iconic children’s book author and illustrator.

Random House Children’s Books will publish Seuss’ Sing the 50 United States! next spring, the press announced in a news release. The manuscript for the book was discovered earlier this year at the Geisel Library at UC San Diego alongside a cover sketch and notes about the art direction; Tom Brannon illustrated the book based on those notes.

Seuss, whose real name was Theodor Geisel, is one of the most enduring creators of children’s literature of all time. His books, including If I Ran the Zoo, The Cat in the Hat, Green Eggs and Ham, and The Lorax, are still staples in homes and classrooms.

Several books by Seuss have been published posthumously, including My Many Colored Days, illustrated by Steve Johnson and Lou Fancher; The Bippolo Seed and Other Lost Stories; and Dr. Seuss’s Horse Museum, illustrated by Andrew Joyner.

Sing the 50 United States!, Random House says, “invites readers to learn and name all fifty states together with the iconic Cat in the Hat and two Little Cat helpers.”

Susan Brandt, the president and CEO of Dr. Seuss Enterprises, said in a statement, “Uncovering a new work from Ted is like finding a time capsule of his imagination. Sing the 50 United States! celebrates his boundless creativity, genius with words, and enduring ability to inspire young readers everywhere. We’re honored to share this new Dr. Seuss treasure with readers across America during such a meaningful milestone year.”

Sing the 50 United States! is slated for publication on June 2, 2026.
