Oceans (French: Océans, also stylized as Ωceans) is a 2009 French nature documentary film directed, produced, co-written, and narrated by Jacques Perrin, with Jacques Cluzaud as co-director. The film, produced in association with the Census of Marine Life, explores the marine species of Earth's five oceans and reflects on the negative aspects of human activity on the environment, with Perrin (Pierce Brosnan in English) providing narration.

Budgeted at around $80 million, it was filmed in over 50 different places and took four years to film. In North America, the film was produced by Disneynature and distributed by Walt Disney Studios Motion Pictures, who cut 20 minutes mostly depicting violent massacres of sea animals (recreated through visual effects) in order to aim it at a younger audience.
