The Lom is a river in the western part of the Danubian Plain of northwestern Bulgaria. A right tributary of the Danube, the river is 93 km long.
The river takes its source at an altitude of 2,100 m on the northern foothills of Midzhur (2,168 m), the highest in the western Balkan Mountains, situated on the Bulgaria–Serbia border. Until the village of Gorni Lom the river flows in direction north–northeast in a deep valley with steep slopes. After receiving its tributary the Stakevska reka and bending northeast, the river valley widens further, reaching 100–200 m at Drenovets. Downstream of Ruzhintsi the valley becomes asymmetrical with well-developed terraces on the left bank and steeper slopes on the right. The river bed is mostly covered with gravel. The Lom flows into the Danube at an altitude of 28 m at the homonymous town.
Its drainage basin covers a territory of 1,240 km2.
