What Country Lies Between Estonia and Lithuania? None—They Share a Border

No country separates Estonia and Lithuania. They share a 339 km (211 mi) land border running east-west across the Baltic region.

• North of the border: Estonia (Valga, Võru counties)
• South of the border: Lithuania (Alytus, Marijampolė counties)
• Tripoint: Estonia–Latvia–Lithuania meet near Valga/Valka (the only Baltic tripoint).

Neighbors

• Latvia lies between Estonia and Lithuania only if you travel west-east along the coast (Gulf of Riga → Latvian corridor → Lithuanian coast). But directly north-south? No country in between.
• Russia (Kaliningrad) borders Lithuania's southwest; Belarus borders Lithuania's southeast/east.

All three Baltics are Schengen, NATO, EU members—border crossing is seamless (pre-2020). Current: random checks possible.
