How We Chose These Books
Every pick is a real, widely available book that shares something specific with Captain Underpants: its tone, its themes, its pace or the kind of characters it puts at the center. We mixed well-known favorites with a few less obvious titles, and we noted who each book suits best so you can match it to the reader. Where a book belongs to a series, we list the first volume so you can start at the beginning.
If you are not sure where to begin, start with the first three picks in the table: they are the closest match to Captain Underpants. The rest of the list moves further out, so it works well once you know which part of the original you liked most. If a pick is part of a longer series, read the first book before you commit, and check the age or content notes in the table before passing a book to a younger reader.
How to Choose
For more Pilkey, Dog Man and Cat Kid Comic Club are the obvious next reads. For silly humor, The Bad Guys, Wayside School and The 13-Storey Treehouse are favorites. Older kids will enjoy Diary of a Wimpy Kid and Big Nate.
