The Bulgaria–Romania border is the state border between Bulgaria and Romania.

For most of its length, the border follows the course of the lower Danube River up until the town of Silistra, where the river continues north into the Romanian territory. East of that point, the land border passes through the historical region of Dobruja, dividing it into Northern Dobruja in Romania and Southern Dobruja in Bulgaria.

The Bulgaria–Romania border is an internal border of the European Union. However, as of 2017 neither country is part of the Schengen Area. As a result, border controls are conducted between the two countries, albeit often jointly (once per crossing).
