HD 73267 b is an extrasolar planet located approximately 164 light-years away. This planet was discovered on October 26, 2008 by Moutou et al. using the HARPS spectrograph on ESO's 3.6 meter telescope installed at La Silla Observatory in Atacama Desert, Chile. In 2022, the inclination and true mass of HD 73267 b were measured via astrometry.
