The Bulgaria–Serbia border separates Bulgaria and the Republic of Serbia in Southeast Europe. It has a length of 341 km (212 mi), of which 315 is on land.[1] The border starts in the North from the tripoint with Romania at the confluence of the Timok and Danube rivers. It then continues southward, first along the Timok river, then continues South until it reaches the tripoint with North Macedonia near Žeravino.
