    854 Frostia is a main-belt asteroid orbiting the sun. It was discovered in 1916 by Sergei Ivanovich Belyavsky from Simiez Observatory in Crimea and is named after Edwin Brant Frost, an American astronomer. This asteroid measures approximately 8.4[1] km in diameter.

    A satellite, designated S/2004 (854) 1, was identified based on light curve observations in July 2004 by Raoul Behrend, Laurent Bernasconi, Alain Klotz, and Russell I. Durkee. It is roughly 10 km in diameter and orbits about 25 km from Frostia with an orbital period of 1.5713 days.
