Belgrade–Bar motorway (Serbian Cyrillic: Ауто-пут Београд–Бар, romanized: Auto-put Beograd–Bar) is a future motorway that will connect the Serbian capital of Belgrade and Bar, Montenegro's main seaport. Italy, Montenegro and Serbia are lobbying to list the route with Pan-European corridors, and it is frequently referred to as part of proposed Corridor XI, or 4B – an envisioned motorway/ferry corridor linking Bari, Bar, Belgrade and Bucharest.
