Sinbad: Legend of the Seven Seas (also known as simply Sinbad) is a 2003 American animated adventure film produced by DreamWorks Animation and distributed by DreamWorks Pictures. Featuring the character Sinbad the Sailor, it was directed by Tim Johnson and Patrick Gilmore (in his feature directorial debut) and written by John Logan, and stars the voices of Brad Pitt, Catherine Zeta-Jones, Michelle Pfeiffer, and Joseph Fiennes. It covers the story of Sinbad (voiced by Pitt), a pirate who travels the sea with his dog and his loyal crew, alongside Marina (voiced by Zeta-Jones), the fiancée of his childhood friend Prince Proteus (voiced by Fiennes), to recover the stolen Book of Peace from Eris (voiced by Pfeiffer) to save Proteus from approving Sinbad's death sentence.

Development began when Ted Elliott and Terry Rossio developed the story of Sinbad in the vein of the story of Damon and Pythias before settling on a love triangle. The project was canceled in 1993, though Jeffrey Katzenberg decided to restart some ideas when he leaved the Walt Disney Company and co-founded DreamWorks Pictures in 1994 during the production of The Prince of Egypt (1998). Johnson, who attempted to direct his follow-up CGI animated film Tusker following Antz (1998), before eventually scrapped the project, was recruited to direct Sinbad and teamed with Gilmore. Like the studio's previous film, Spirit: Stallion of the Cimarron (2002), the film combines traditional animation and computer animation. The film blends elements from One Thousand and One Nights and classical mythology. The film's traditional animation and its final line services were provided by Stardust Pictures and Bardel Entertainment, with PDI/DreamWorks handling its computer animation technology and CG character animation.

Sinbad was released on July 2, 2003, and received mixed reviews from critics, who praised the animation, action sequences, and voice performances, but criticized the storyline, polarizing CGI, and the film's departure from its Arabic origin. Grossing $80.8 million on a $60 million budget, Sinbad was a box-office bomb, causing DreamWorks to suffer a $125 million loss on a string of films, which nearly bankrupted them. To date, this soon became the final DreamWorks Animation film to use traditional animation, and hand-drawn animation as the studio abandoned and discontinued them in favor of 3D animation. However, DreamWorks brought 2D animation back for the 5-minute short film Bird Karma in 2018.
