The Ohm Hills (German: Ohmgebirge) are a small range of hills up to 533.4 m above sea level (NN) high and about 50 km² in area. They are part of the Lower Eichsfeld region and are located in the county of Eichsfeld, North Thuringia, Germany.

The Ohm Hills, most of which are densely wooded, whose southeastern foothills form the Bleicherode Hills, lie in the county of Eichsfeld on its boundary with Nordhausen. They are located between Weißenborn-Lüderode to the north, Bleicherode to the southeast, Worbis to the south and Teistungen to the west, and extend from the upper reaches of the River Helme in the north to the Wipper in the south. To the north and west the range is adjoined by historic landscape of the Lower Eichsfeld (Untereichsfeld), further south is the ridge of the Dün and to the southwest the Eichsfeld-Hainich-Werra Valley Nature Park.

According to "Kassel map" of the natural regional classification of Germany the Ohm Hills are grouped as follows:

• (to 37 Weser-Leine Uplands, Lower Saxon Hills)
  • (375 Lower Eichsfeld)
    • 375.2 Ohm Hills and Bleicherode Hills

The Thuringian State office for the Environment and Geology uses a rather coarser, self-published, region classification, within which the landscape of "Ohm Hills-Bleicherode Hills" is enclosed by the landscape unit "North Thuringian Buntsandstein Land".

The muschelkalk ridges of the Ohm Hills and Bleicherode Hills are shown in both classifications as one contiguous natural region. They appear as a continuation of the hills fringing the northwestern perimeter of the Thuringian Basin interrupted only by the Lower Eichsfeld lowland.

Neighbouring natural regions listed clockwise are:

• Lower Eichsfeld including the Eichsfeld Bowl (Eichsfelder Kessel) to the south and the Zehnsberg to the west
• Eichsfeld Basin (Eichsfelder Becken) with the Duderstadt Basin to the northwest and the hill country of the Hellberge to the north
• Silkerode Hills on the far side of the Geroder Eller to the northeast
• North Thuringian Hills to the east

The rivers and streams in the Ohm Hills include the:

• Hahle, rises at the southern edge of the Ohm Hills in Worbis, passes to the south, southern tributary of the Rhume
• Helme, rises in the northern foothills of the Ohm Hills, leaves them head east, western tributary of the Unstrut
• Wipper, rises on the southern edge of the Ohm Hills in Worbis, passes them to the east, western tributary of the Unstrut
• Bode, rises in the Ohm Hills, leaves them heading east, southwestern tributary of the Wipper

The Elbe-Weser Watershed runs through the Ohm Hills. Whilst the Hahle is part of the catchment area of the Leine and Weser rivers, the Bode, Helme and Wipper are in the Elbe's drainage basin.
