Širvinta , is a river in southwestern Lithuania (and part of the border with Kaliningrad Oblast, Russia), a left tributary of Šešupė.
It begins in Vilkaviškis District Municipality, west of the village of Alvitas, and flows northwest in its upper reaches. From the confluence with the Liepona, the river flows north, then northeast, forming about 20 kilometres (12 mi) of the Lithuania–Russia border. The river then passes the Širvinta bridge built by the Germans in Kudirkos Naumiestis, and flows into the Šešupė, at a total length of 43.8 km (27.2 mi).
