Oh, the Places You'll Go! is a book written and illustrated by children's author Dr. Seuss. It was first published by Random House on January 22, 1990, making it his last book published before his death. The book concerns the journey of life and its challenges.

Though written in the style of classics such as Green Eggs and Ham and The Cat in the Hat, Oh, the Places You’ll Go! has many specific characters including a narrator and the reader. A young boy, referred to simply as "you", initiates the action of the story. However, the presence of a main character helps readers to identify with the book. It is written in second person and uses future tense.

It is perhaps best known for the line, "Will you succeed? Yes, you will indeed. (98¾% guaranteed.)" It also features Seuss's trademark creative use of the English language, as in, "Simple it's not, I'm afraid you will find, for a mind maker-upper to make up his mind."
