Get ready to rhyme your way through all 50 states. A brand-new Dr. Seuss book is hitting shelves next summer, just in time for America’s 250th birthday.
It’s called “Sing the 50 United States!” and stars the one and only Cat in the Hat, who’s trading in his usual antics for a musical geography lesson. The book will help kids (and probably some adults) learn the names of every U.S. state, Dr. Seuss–style.
Even though the book’s new to us, it’s actually an old treasure that was recently rediscovered. A complete manuscript was found in Dr. Seuss’ archives in San Diego, along with a cover sketch and his own notes on the art direction. Think of it like opening a time capsule from the mind of Theodor Seuss Geisel himself.
Dr. Seuss Enterprises CEO Susan Brandt 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.”
The book will be released June 2nd, 2026, but it’s already available for preorder wherever books are sold. There will also be a special music video to go along with it on the Dr. Seuss YouTube channel.
If this sounds familiar, that’s because it’s not the first time a posthumous Dr. Seuss book has been discovered.
The last one, “What Pet Should I Get?”, came out in 2015, nearly a quarter-century after his passing in 1991.
Dr. Seuss’ stories have always found ways to spark joy and curiosity across generations, and this latest surprise should be no different. With the Cat in the Hat back on the scene and a patriotic singalong to boot, this feels like a perfectly Seussian way to celebrate America’s big milestone year.
