Estonia–Lithuania relations refer to the bilateral relations between Estonia and Lithuania. Estonia has an embassy in Vilnius. Lithuania has an embassy in Tallinn. Both countries are situated in the Baltic region and are the full members of NATO and the European Union.
Present-day southern Estonia was part of the Polish–Lithuanian Commonwealth from the 1560s to the 1620s with the cities of Tartu and Pärnu being provincial capitals. It endured Swedish invasions during the Polish–Swedish wars of 1600–1611, 1617–1618 and 1621–1625.
Lithuania and Estonia officially established diplomatic relations on 2 March 1921. Following the Soviet occupation after the World War II, both states continued the diplomatic service in exile. After the independence restoration, the relations were re-established de facto on 16 June 1991.
Many of the agreements between the two countries are trilateral with Latvia as the three Baltic states.
In 2004, the free trade agreement signed in 1992 between the Baltic states was superseded when all three countries joined the European Union..[1]
In 2017, the two countries along with Latvia, signed a rail agreement. The agreement is a precondition for a possible high speed railway between the states.[2]
