The Lithuania–Poland border is the state border between the Republic of Lithuania and the Republic of Poland. The length of the border is 104 kilometres (65 mi). It runs from the Lithuania–Poland–Russia tripoint southeast to the Belarus–Lithuania–Poland tripoint. It is an internal border of the European Union and the Schengen Zone.

It is the only land border that one of the Baltic states (which are members of the EU and NATO) shares with a country that is not a member of the Commonwealth of Independent States.
