The Belarus–Lithuania border is an international border almost 678.8 km (421.8 mi) in length between the Republic of Belarus (CIS member) and the Republic of Lithuania (EU member). It is an external border of the European Union as well as the western border of the Commonwealth of Independent States. 379.9 km (236.1 mi) of the border is on land, while 298.9 km (185.7 mi) are on water, crossing lakes, e.g. Lake Drūkšiai and following some rivers, e.g. Dysna River and Neman River.
In August 2022, Lithuania completed the construction of a new border barrier to stop illegal migration. On 18 January 2023, the Lithuanian government renounced the agreement signed with Belarus 16 years ago on the principles of cross-border cooperation.
