Steimbke is a municipality in the district Nienburg, in Lower Saxony, Germany. It is situated approx. 12 km east of Nienburg, and 40 km northwest of Hanover, in a swamp and heathland, whereas the Blindesee takes centre stage.
In development of the village, the industrial union "Gewerkschaft Brigitta" had the greatest share in 1934 by beginning oil production. "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. By the date of June 30, 2005, Steimbke had a population of 2.739.
