Homberg (Ohm) (German pronunciation: [ˈhɔmbɛʁk] ⓘ) is a town in the Vogelsbergkreis in Hesse, Germany.

The officially recognized climatic spa of Homberg lies from 203 to 350 m above sea level in the valley of the Ohm, a tributary to the Lahn, some 19 km southeast of Marburg.

Until the 16th century, the town's arms generally showed a castle or town wall with the red-and-silver-striped Lion of Hessen, and in 1536, a new version suddenly showed the lion "sinister" – facing left (from the arms bearer's point of view).

The busline VB-71 run by the Verkehrsgesellschaft Oberhessen (Upper Hessen Transport Company) also goes to Gemünden, and line VB-13a offers a direct connection to Alsfeld railway station.

The Ohmtalbahn, which runs through Homberg (Burg- and Nieder Gemünden–Kirchhain) is nowadays only partly in service beginning at Nieder-Ofleiden, and only then for goods trains that serve a basalt quarry.
