Steimbke is a municipality in the district Nienburg, in Lower Saxony, Germany.

It is situated approximately 12 km east of Nienburg, and 40 km northwest of Hanover, in a swamp and heathland, whereas the Blindesee takes centre stage.

Since the local election on 10 September 2006, two parties and one Wählergemeinschaft represent it.

"Brigitta" established an estate for industrial workers with bounteous sports facilities, a stadion with flood light and an indoor- as well as an outdoor swimming pool.

In the meantime, the reduction of oil production has resulted to the abolishment of the pumpjacks that in former times have been Steimbke's landmark.
