100 Hekate (hek'-ə-tee, IPA: /ˈhɛkəti/) is a large Main belt asteroid. It orbits in the same region of space as the Hygiea asteroid family, however it is actually an unrelated interloper. Its albedo of 0.19 is too high, and it is of the wrong spectral class to be part of the dark carbonaceous Hygiea family.
Hekate was the 100th asteroid to be discovered, by J. C. Watson on July 11, 1868. It is named after Hecate, the goddess of witchcraft in Greek mythology, but its name also commemorates it as the hundredth asteroid, as hekaton is Greek for 'hundred'.
A Hekatean occultation of a star was observed on July 14, 2003 from New Zealand.
