All the Captain Underpants Books, Ranked Best to Worst

While the series has faced its fair share of controversy, every Captain Underpants book at least elicits a strong reaction (for better or for worse). Despite being one of the most frequently banned children's books, Captain Underpants has prevailed as a staple of children's literature. While Dav Pilkey's series has been condemned for its potty humor, consider the target audience. The books are catered to very young children, likely still carefree enough to laugh at designations like "Professor Pippy Pee-Pee Poopypants." Over the course of 12 books, fans have delighted in seeing the adventures of a curmudgeon principal-turned-superhero unfold. If you're wondering which book to read first, here you'll find all Captain Underpants books ranked by user votes! 

Out of the many Captain Underpants books, which one is the best? The first installment of the series, simply titled The Adventures of Captain Underpants, became an instant hit with children between six and eight. The last installment, Captain Underpants and the Sensational Saga of Sir Stinks-A-Lot, received widespread praise for portraying non-traditional families when it casually revealed a main character was gay. For these and other great titles in the series, browse this list!
