HD 132406 b is a long-period, massive gas giant exoplanet orbiting the Sun-like star HD 132406. HD 132406 b has a minimum mass 5.61 times the mass of Jupiter. The orbital distance from the star is almost twice that of from Earth to the Sun. The orbital period is 2.7 years.[1]

An astrometric measurement of the planet's inclination and true mass was published in 2022 as part of Gaia DR3,[3] and this was updated in 2023.[2]
