A Trip to the Moon (French: Le voyage dans la lune [lə vwajaʒ dɑ̃ la lyn]) is a 1902 French science-fiction adventure trick film written, directed and produced by Georges Méliès. Inspired by Jules Verne's 1865 novel From the Earth to the Moon and its 1870 sequel Around the Moon, the film follows a group of astronomers who travel to the Moon in a cannon-propelled capsule, explore the Moon's surface, escape from an underground group of Selenites (lunar inhabitants), and return to Earth with a captive Selenite. Méliès leads an ensemble cast of French theatrical performers as the main character Professor Barbenfouillis.

Although the film disappeared into obscurity after Méliès's retirement from the film industry, it was rediscovered around 1930, when Méliès's importance to the history of cinema was beginning to be recognised by film devotees. An original hand-colored print was discovered in 1993 and restored in 2011.

A Trip to the Moon was ranked 84th among the 100 greatest films of the 20th century by The Village Voice. The film remains Méliès' best known, and the moment when the capsule lands in the moon's eye remains one of the most iconic and frequently referenced images in the history of cinema.
