Epsilon Eridani c is an unconfirmed extrasolar planet approximately 10 light-years away in the constellation of Eridanus. The planet was announced to be orbiting the orange dwarf star Epsilon Eridani in 2002, but is currently considered unconfirmed. If confirmed, Epsilon Eridani would be classified as the closest planetary system to the Sun, while Epsilon Eridani c would be the first confirmed Jovian planet with an insolation similar to that of NeptuneFact|date=August 2008.

Proposed in 2002 based on analysis by Alice Quillen and Stephen Thorndike of the structure of the dust disk around the star. Clumping in the dust disk can be modelled by dust particles being trapped in resonances with a planet in an eccentric orbit.
