Kef Bir, designated IX3244-C and known as the Ocean Moon of Endor, was an oceanmoonorbiting the gas giantEndor in the Endor system. Jannah, a humanfemale freedom fighter who, by the time of the First Order-Resistance War, led a tribe of brave and noble warriors, lived on the moon after the tribe mutinied at the Battle of Ansett Island. Some of the wreckage of the second Death Star was located on Kef Bir.

An oceanmoon, Kef Bir orbited the planetEndor, in the Endor system of Outer Rim Territories‘ Moddell sector, positioned at the coordinates H-16 on the Standard Galactic Grid. The moon used to be almost entirely underwater, until several cataclysmic events had vented the water into the atmosphere and caused tectonic upheaval, that revealed more and more landmasses. Since then it was primarily covered by oceans, such as the Kef Sur ocean, and grassland islands, such as the Angkuadi islands. The moon had at least one continent, called Shoduah. At high tide, the waves could reach a height of over 120 meters. It had a saline environment .

Kef Bir first appeared in the 2019 sequel trilogy film, Star Wars: Episode IX The Rise of Skywalker. Footage was recorded in Buckinghamshire, England, and then digitally transformed into the stormy coast seen in the movie.

On October 23, 2019, the Disney Parks Blog announced that the Star Tours: The Adventures Continue rides at Disneyland, Walt Disney World, Disneyland Paris and Tokyo Disneyland would be updated to include a scene set on Kef Bir, similar to previous updates that added planets featured in The Force Awakens and The Last Jedi.
