How the Grinch Stole Christmas! is one of the best-known children's books by Dr. Seuss. It is written in rhymed verse, with illustrations by the author. It showcases the famous character, The Grinch, and has been adapted to other media, also discussed below.

Seuss completed How the Grinch Stole Christmas! in 1957.

Dr. Seuss' How the Grinch Stole Christmas! also known as The Grinch is a 2000 live-action film, based on the 1957 book and television special of the same name by Dr. Seuss. Due to additions made to the storyline so that it could be brought up to feature-length, it was considerably less faithful to the original book and subsequent animated short, creating a new back-story to explain the Grinch's motivations and reasons behind his hatred of the Christmas season and its cheerful nature. The film was directed by Ron Howard, produced by Brian Grazer, and starred Jim Carrey in the title role of the Grinch. Taylor Momsen starred as Cindy Lou Who, who in this version seems to be about eight years old, where the character in the book and TV special was "no more than two". While this version is often referred to as simply The Grinch, the on-screen title is How the Grinch Stole Christmas, with the words "The Grinch" written in much larger letters than the rest of the title, and the "!" isn't seen like it was in the book and TV special. The movie received mixed critical reaction but spent four weeks as the #1 film in the U.S. and eventually earning $260 million at the US box office. It has since been aired annually on ABC Family as part of The 25 Days of Christmas.

Other cast members include the late Josh Ryan Evans as the young Grinch, Bill Irwin as Lou Lou Who, Jeffrey Tambor as Mayor Augustus May Who, and Christine Baranski as Martha May Whovier.

Bitter and hateful, the Grinch is irritated at the thought of the nearby village having a happy time celebrating Christmas. So disguised as Santa Claus, with his dog made to look like a reindeer, he raids the village to steal all the Christmas things. The village is sure to have a sad Christmas this year.
