üstra Hannoversche Verkehrsbetriebe AG is the operator of public transport in the city of Hanover, Germany.

The company also provided electricity to private customers as well as operating bus and tram services - not only in the city of Hannover but also to the outlying villages and small towns.

The rural tram lines which were mostly singletrack brought coal (from Barsinghausen), milk and farm produce to the city but this business dwindled down with the motorisation in the 1950s and 1960s.

In 2001, ownership of the rail network, tunnels and stations of the Hanover Stadtbahn was transferred to Infrastrukturgesellschaft Region Hannover GmbH.

üstra had transferred more than 1900 employees to intalliance and acted as a holding company, having owned significant shares in intalliance AG, the TransTec holdings (providing technical services) and the protective service GmbH (the former security branch of üstra).
