The Eula () is a tributary of the River Wyhra in northwestern Saxony in Germany. It has a length of and a catchment area of about .
The Eula rises in the Eulawäldchen ("Little Eula Wood") south of the Geithain parish of Wickershain. It crosses the municipality of Geithain, flowing through the lido of Oberfürstenteich. Beyond Geithain it collects the Salzbach from the left and the Kalkbach from the right. After passing through Niedergräfenhain, Frauendorf and Hermsdorf it reaches PrieÃÂnitz. Here it is joined from the right by the Frankenheimer Bach and the Little (Kleine) Eula. Next it flows through FlöÃÂberg and Beucha to Kitzscher, collecting the Heinersdorfer Bach and Steingrundbach before reaching Beucha.
Whilst the Eula has been straightened for long stretches, there is a near natural reach between Beucha and Kitzscher with meanders, sand banks and kolks.
After collecting the Jordanbach in Kitzscher it turns from its hitherto predominantly northwesterly course to head in a southwestern to western direction. Flowing past (a parish of Kitzscher), (a parish of Kitzscher) and (a parish of Borna), where since 2009 it has once more flowed for half a kilometre on its old, winding river bed, the river passes under the B 95 federal road. It then continues between Haubitz and the and after empties near GroÃÂzössen into the Wyhra, which then reaches its confluence with the PleiÃÂe after just two more kilometres.
