阿特巴拉河（阿拉伯语：نهر عطبرة‎；罗马化：Nahr 'Atbarah）发源于非洲东北部的埃塞俄比亚西北，塔纳湖以北约50公里和贡德尔以西30公里，流经805公里（500英里），在苏丹中北部的阿特巴拉（17°40′37″N 33°58′12″E / 17.677°N 33.970°E / 17.677; 33.970）跟尼罗河汇合，支流特克泽河可能是阿特巴拉河的真正上游部分，因为特克泽河在汇合前的河道较长。

在尼罗河流入地中海前，阿特巴拉河是最后一条流入尼罗河的支流。阿特巴拉河在全年大部分时间与小溪无异，只在夏天雨季有大的流量。

The Atbarah River (Arabic:نهر عطبرة‎; transliterated: Nahr 'Atbarah) in northeast Africa rises in northwest Ethiopia, approximately 50 km north of Lake Tana and 30 km west of Gondar. It flows about 805 km (500 mi) to the Nile in north-central Sudan, joining it at the city of Atbarah (17°40′37″N 33°58′12″E / 17.677°N 33.970°E / 17.677; 33.970). Its tributary, the Tekezé River, is perhaps the true upper course of the Atbarah, as the Tekezé follows the longer course prior to the confluence of the two rivers (at 14° 10' N, 36° E) in northeastern Sudan. The Atbarah is the last tributary of the Nile before it reaches the Mediterranean.
