南极绕极流（英语：Antarctic Circumpolar Current，ACC），或称为西风漂流、南极环流，为一个环绕南极洲由西向东的洋流。南极绕极流为南冰洋的主要循环系统特征。这令温暖的海水隔离南极洲，令其大陆维持其巨大冰原。

南极绕极流被水手们广泛认知多年。杰克·伦敦的 "Make Westing" 深刻地刻划出快帆船（clipper ship）上水手们在纽约至加利福尼亚的航在线绕过合恩角的困难。

The Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and has a mean transport of 100-150 Sverdrups (Sv, million m³/s), making it the largest ocean current. The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet.
