The Thyra is a {{convert|20|km|mi|adj=mid|-long}} river of Saxony-Anhalt, Germany, in the district of Mansfeld-Südharz in the Harz Mountains.

== Course ==

The Thyra begins its course in the old quarter of Stolberg in the Harz Mountains at the confluence of three mountain streams - the Große Wilde, Kleine Wilde and Lude[http://www.harzlife.de/special/thyra.html Harzlive - Thyra] - and then flows through Stolberg, where several streams join it, before heading south through a steep valley to Rottleberode. Here the Thyra valley becomes very wide, but near Uftrungen it narrows again. South of Uftrungen the Thyra leaves the Harz and enters the Goldene Aue, crossing {{ill|Bösenrode|de}} and Berga, before this little river enters the Helme.
