The Steina Dam (German: Steinatalsperre) in the Harz Mountains of central Germany is a dam system comprising a dam, reservoir and waterworks near the village of Steina and belongs to the unincorporated area of Harz in the district of Göttingen in Lower Saxony.
The dam was inaugurated on 19 November 1954 as a retention basin and has been a drinking water reservoir since 1958. Its 8.5 metre high dam impounds the Steina stream forming the Steina Reservoir (Steinastaubecken). It provides drinking water for the villages of Bad Sachsa, Osterhagen, Nüxei and Steina, which is why the surrounding woods are a water protection area.
