14 Herculis c is an extrasolar planet 59 light years away from Earth. It was discovered on November 17, 2005 and confirmed on November 2, 2006. The planet is a gas giant, and has a mass that would make it roughly the same size as Jupiter, but much more massive.

According to a recent analysis, the existence of a second planet in the 14 Herculis system is "clearly" supported by the evidence, but the planet's parameters are not precisely known. It may be in a 4:1 resonance with the inner planet 14 Herculis b.
