HD 48265 b is an extrasolar planet located approximately 285 light-years away in the constellation of Puppis, orbiting the 8th magnitude G-type main sequence star HD 48265. This planet has a minimum mass of 1.2 times that of Jupiter. Because the inclination is not known, the true mass is not known. This planet orbits at a distance of 1.6 AU with an orbital eccentricity of 0.24.
