Kiffu was a world situated within the Inner Rim territories of the galaxy, recognized as a planet. Along with Kiffex, it served as one of the two origin worlds for the Kiffar species, a sentient race. This was the homeworld of Quinlan Vos, a Kiffar Jedi Master who served within the Jedi Order starting at least 32 years prior to the Battle of Yavin until the conclusion of the Clone Wars; he also lived through the Great Jedi Purge and aided the clandestine organization known as the Hidden Path up to at least 9 BBY.
The initial depiction of Kiffu occurred in the 20th issue of the Star Wars: Republic comics series, titled Star Wars (1998) 20, where it was identified as Quinlan Vos's planet of origin. Although this comic series is now classified as part of the Star Wars Legends continuity, Kiffu was confirmed as Vos's birthplace in Ultimate Star Wars, a canon reference book for the Star Wars universe that was made available to the public on April 28, 2015. Subsequently, the Databank on the StarWars.com site included an entry for the Kiffar, explicitly stating that Kiffu and Kiffex were the two planets the species originated from.
