Kepler-37d is an exoplanet discovered by the Kepler space telescope in February 2013. It is located 209 light years away, in the constellation Lyra. With an orbital period of 39.8 days, it is the largest of the three known planets orbiting its parent star Kepler-37.

A 2021 study detected Kepler-37d via radial velocity, finding a mass of about , but a 2023 study instead found an upper limit on its mass of only . In either case, it is not a rocky planet, but a low-density planet rich in volatiles.
