Rossert is a mountain of the Taunus, part of the Anterior Taunus, in Hesse, Germany.

The mountain consists of a few hilltops, two of them giving the name the Naturschutzgebiet (protected area) Rossert - Hainkopf - Dachsbau.

Between them lies Eppenhain, a constituent community of Kelkheim.

The name Rossert originates from an Old High German word for cobblestones.
