Epsilon Andromedae (Epsilon And, ε Andromedae, ε And) is a G-type giant star in the constellation of Andromeda. It has an apparent visual magnitude of approximately 4.37.

ε Andromedae is believed to be a red clump star which is fusing helium in its core. Its orbit in the Milky Way is highly eccentric, causing it to move rapidly relative to the Sun and its neighboring stars.
