This desert planet, located within the Si'Klaata Cluster, is the homeworld of the Klatooinan race. Klatooine is found deep in Hutt space.

Native to Klatooine, the Klatooinans have been indentured to the Hutts since before the rise of the Old Republic. Along with the Vodran and Nikto races, the Klatooinans have served the Hutts since the battles against Xim the Despot. They are a tall, humanoid race with flat, canine faces and coarse skin. The Klatooinan culture is strongly tied to traditional values and has been as patient and tenacious as the Fountain of Ancients. They also, like the Fountain, strove to grow stronger with age. The Klatooinans have often referred to themselves as the Children of the Fountain since they have developed many of the Fountain's characteristics. At the age of ten, every Klatooinan is sold into servitude, usually to local governments. Especially troublesome youths are sold into slavery. This helps the young Klatooinans learn to respect and admire their elders and the traditions of their people. However, they have forever been under the oppression of the Hutts. Like the Fountain of the Ancients, the Klatooinans hope that they can endure long enough to grow strong with age and shed the Hutt yolk.

The Fountain of the Ancients is a unique, natural phenomenon located in the center of the Derelkoos Desert, on Klatooine. In a bowl-shaped depression, liquid wintrium seeps from the desert sand and begins to crystallize. As it solidifies over several millennia, the wintrium forms wonderful shapes and patterns, continually expanding and growing. Because of its hardness, the Fountain's shape can be altered only by powerful weaponry and has stood untouched for as long as the Klatooinan race can remember. The Fountain's continual growth, increasing strength, and tenacity have instilled similar values in the Klatooinan people. It also has certain religious connotations to them. Wintrium this glass-like substance remains in liquid form at very low temperatures and can take as much as 10,000 years to solidify under normal conditions. It is found in the Derelkoos Desert of Klatooine, where it seeps from the desert and creates incredibly beautiful, natural sculptures. The Klatooinans call the landmark the Fountain of the Ancients and revere it for its tenacious and wonderful existence.

Paddy Frogs are flat, bloated amphibians are native to the planet Klatooine. The Hutts used to consume these creatures as appetizers. He preferred them preserved in brandy, which added flavor and kept these vicious little frogs from attacking each other.
