Epsilon Tauri b is an extrasolar planet approximately 155 light-years away in the constellation of Taurus. The massive planet was discovered in orbit around star Epsilon Tauri. It orbits the star further out than Earth orbits the Sun. It has moderate eccentricity.

The planet orbits one of the four giant stars in the Hyades cluster that is 2.7 times the mass of our Sun, making it the most massive planet-harboring star. This provides evidence that it was an A-type star when it was a main-sequence.

The inclination of the orbit is not known. This object would probably be a brown dwarf instead.
