Gliese 667 Cg is an unconfirmed exoplanet orbiting the star Gliese 667 C, which is a member of the Gliese 667 triple star system. Gliese 667 Cg has a minimum mass of 4.41 Earth masses, and cannot be more than 8.82 Earth masses. It is likely an ice planet, with the possibility of a subsurface ocean. Its existence has yet to be confirmed.

Re-analysis of the data by Feroz and Hobson (2014) indicates that the detection of this planet was actually a result of failing to properly account for correlated noise in the radial-velocity data.
