阿古拉斯洋流（Agulhas current）是印度洋西南部的西边界流（western boundary current），沿着非洲东岸从27°S 流至 40°S。该洋流窄、急而强；有人甚至认为它可能是世界大洋中最大的西边界流，其净流量大概为100斯维尔德鲁普(Sv)，其它可与之相比的西边界流流量都相对较小，如巴西洋流为16.2Sv，黑潮为42Sv。

The Agulhas Current /əˈɡʌləs/ is the western boundary current of the southwest Indian Ocean. It flows down the east coast of Africa from 27°S to 40°S. It is narrow, swift and strong. It is even suggested that the Agulhas is the largest western boundary current in the world ocean, with an estimated net transport of 70 Sverdrups (Sv, millions m/s), as western boundary currents at comparable latitudes transport less — Brazil Current (16.2 Sv), Gulf Stream (34 Sv), Kuroshio (42 Sv).
