The Belarus–Lithuania border is an international border almost 679 km and is the outer border of the European Union and the western border of the Commonwealth of Independent States. The border is based on the border between the Lithuanian Soviet Socialist Republic and Byelorussian Soviet Socialist Republic within the Soviet Union, which had remained largely stable since 1940.

Areas accessible to the border such as through villages and close to roads were the first areas to be fenced off. This point at Dailides near the village of Dieveniskes, was fenced off in 2003 before Lithuania entered the EU and was visited at that time by fellow border enthusiasts here.
