Leda is a river in north-western Germany in the state of Lower Saxony.
The Leda is a right tributary of the Ems and originates at the confluence of the Sagter Ems and the Dreyschloot (a branch of the Soeste) near Barßel. The Leda flows into the Ems near the town of Leer. On the southern bank of the Leda, in the Overledingen Land (Overledingen="country over the Leda"), opposite Leer, lies the small settlement of Kloster Muhde (Muhde from the Old Frisian mutha meaning "(river) mouth"). The total length of the river is 24.2km (15miles) (72.3km (44.9miles) including the source rivers Sagter Ems and Ohe).
