HD 187085 b is an extrasolar planet discovered in 2006 by a team led by Hugh Jones. HD 187085 b orbits its star in a highly eccentric orbit. The discovery was made as part of the Anglo-Australian Planet Search.

Their interpretation of the data set the eccentricity at 0.47. Using a statistical computer program, another team reinterpreted the same data for a lower eccentricity of 0.33.
