Kappa Coronae Borealis b is a jovian planet approximately 102 light years away in the constellation of Corona Borealis. This planet was discovered by Johnson et al., who used the radial velocity method to detect wobbling of the star caused by a planet move around by its tug of gravity. It was first discovered in September 2007 and was published in November.

The planet has mass of 1.8 Jupiter masses or 570 Earth masses. Although only the minimum mass is known since the inclination is not known. It orbits at a distance of 2.7 astronomical units or 400 gigameters and takes 1208 days or 3.307 years to orbit around Kappa Coronae Borealis.
