The Founders are a political entity in the fictional Star Trek universe. They are the creators and rulers of the Dominion. The Founders consist of all but 100 of the Changelings. (The rest, which include Constable Odo, are collectively known as The Hundred).

For many years, the Founders were considered mythical by many of the races in the Dominion, although their policy was enforced by the Vorta and the Jem-Hadar . It was not until 2371 , when Odo discovered the changelings' homeworld in the Omarian Nebula , that the Founders' true status was revealed.
