Ihme (in its upper course: Wennigser Mühlbach) is a river of Lower Saxony, Germany. It is a left tributary of the Leine.

The Ihme is 26 kilometres (16 mi) long. Its source is in the village Evestorf [de], a district of Wennigsen. After about 6 kilometres (4 mi), the Ihme reaches the city of Hanover, where it flows into the Leine. In order to protect the city center of Hanover from flooding, much of the water of the Leine is rerouted by a ditch into the Ihme. A bridge over the Ihme is named in memory of Benno Ohnesorg.

The Ihme gives its name to the village Ihme, that forms together with Roloven the district Ihme-Roloven [de; fr] of Ronnenberg.
