1972 television special
The book was adapted as an animated musical television special produced by DePatie-Freleng Enterprises, directed by Hawley Pratt and starring the voices of Eddie Albert and Bob Holt. It was first aired by CBS on February 14, 1972. A reference to pollution of Lake Erie was spoken by one of the Humming-Fish as they depart; it remains in DVD releases of the show, although later removed from the book. The special also shows the Onceler arguing with himself, and asking the Lorax whether shutting down his factory (thus putting hundreds of people out of work) is practical. An abridged version of the special is used in the 1994 TV movie In Search of Dr. Seuss, with Kathy Najimy's reporter character hearing the Once-ler's story.
2012 feature film
Universal Pictures and Illumination Entertainment released a 3D CGI film based upon the book. The Lorax was released on March 2, 2012; the release coincided with the 108th birthday of Seuss, who died at 87 in 1991. The cast includes Danny DeVito as the Lorax, Zac Efron as Ted (the boy in the book), and Ed Helms as the Once-ler. The film includes several new characters: Rob Riggle as villain Aloysius O'Hare, Betty White as Ted's Grammy Norma, Jenny Slate as Ted's neurotic mother Mrs. Wiggins, and Taylor Swift as Audrey, Ted's romantic interest. The film debuted in the No. 1 spot at the box office, making $70 million, though it received mixed reviews. The film eventually grossed a domestic total of $214,030,500.[17] Danny DeVito did his role in five different languages, including the original English audio, and also for the Russian, German, Italian, Catalan/Valencian, Castillan Spanish and Latin Spanish dub editions, learning his lines phonetically.

Musical
A musical adaptation of The Lorax was originally included in the script for the Broadway musical Seussical, but was cut before the show opened.[18]
From December 2, 2015, to January 16, 2016, a musical version of the book ran at the Old Vic theatre in London, with former Noah and the Whale frontman Charlie Fink, who also wrote the music for the production.[19]
From July 2 to August 12, 2018, the musical ran at the Old Globe Theatre San Diego, California with Steven Epp as The Once-ler. The role of the hero to be trusted with the last seed, a boy in the original book, was filled by a girl in the musical.[20]
