HD 74156 c is an extrasolar planet with a minimum mass about eight times that of Jupiter orbiting the star HD 74156. It is most likely a gas giant. This planet was discovered by Dominique Naef and Michel Mayor in April 2001 together with the planet HD 74156 b.[2][1] In 2022, the inclination and true mass of HD 74156 c were measured via astrometry.[3]
