Ubuntu JeOS (acronym pronounced "juice"; short for just enough operating system) is a discontinued variant of Ubuntu Linux that is described as "an efficient variant ... configured specifically for virtual appliances." It is a concept for what an operating system should look like in the context of a virtual appliance. JeOS has been replaced by Ubuntu Core, which is now an officially supported minimal variant of Ubuntu.

Its first release was Ubuntu JeOS 7.10, and since the release of Ubuntu 8.10 it has been included as an option as part of the standard Ubuntu Server Edition.
