Vanadis (minor planet designation: 240 Vanadis) is a fairly large main-belt asteroid. It is very dark and is classified as a C-type asteroid, probably composed of primitive carbonaceous material.

It was discovered by A. Borrelly on August 27, 1884, in Marseilles and was named after Freyja (Vanadis), the Norse fertility goddess.
