704 Interamnia ("IN ter AM nia") is a very large asteroid with a diameter of 350 kilometres. Its mean distance from Sun is 3.067 (AU). It was discovered on October 2, 1910 by Vincenzo Cerulli, and named after the Latin name for Teramo, Italy, where Cerulli worked.

Interamnia is the sixth largest known asteroid within Jupiter's orbit and was discovered surprisingly late for such a large object.
