Lithuania–Poland border, International border between Lithuania and Poland.
The Lithuania-Poland boundary runs about 104 kilometers through forested terrain and rolling hills, forming a natural dividing line between the two countries. The area is crossed by several official passage points, including road routes and a railway line that handle both passenger and cargo movement.
The modern boundary was established through the Suwałki Agreement of 1920, when both nations gained independence after World War I and needed to settle territorial claims. Since then it has remained a stable border between two sovereign states and today contributes to the internal structure of the European Union.
The boundary is a place where people regularly cross between the two nations, with local communities maintaining strong ties and family connections. Residents move freely across for work and daily activities, making the area a living connection between Lithuanian and Polish life.
Travelers can cross at one of four official passages that are regularly open and process both pedestrians and vehicles. It is useful to carry valid travel documents and check local road conditions in advance, as the area is rural with limited services.
The boundary is part of the strategic Suwałki Gap, a narrow passage between Belarus and the Russian exclave of Kaliningrad. This area plays a role in European security discussions, though it presents itself as peaceful countryside to visitors.
