854 Frostia is an asteroid orbiting the Sun. It is named after Edwin Brant Frost, an American astronomer.

A satellite, designated S/2004 (854) 1, was identified based on lightcurve 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 in 1.5713 days.
