阿拉斯加洋流是一股沿着美国阿拉斯加州海岸往北的太平洋温暖暖流，由北太平洋洋流因为北美洲海岸线的关系而被分出来。阿拉斯加洋流是一种表面流，是西风漂流的一股，在阿拉斯加湾内逆时针运行的环流。阿拉斯加洋流与一般的亚极地不太相同，它的水温为4 °C（39.2 °F）而盐度为千份之32.6。阿拉斯加为暖流。

The Alaska Current is a southwestern warm-water current along the coast of British Columbia and the Alaska Panhandle. The current results from the northward diversion of a portion of the North Pacific Current when that current meets the west coast of the North American continent. It forms a part of the counterclockwise gyre in the Gulf of Alaska. In contrast to typical sub-Arctic Pacific water, Alaska Current water is characterized by temperatures above 39°F (4°C) and surface salinities below 32.6 parts per thousand.
