北太平洋洋流( 英语：North Pacific Current )，或称北太平洋漂流，是一股位于太平洋约北纬40度左右的洋流，为北太平洋近极环流的一部份。北太平洋洋流是由沿着日本东部海岸北向的黑潮与来自北极南向的亲潮会合而成。最后在美国与加拿大交界处分为北向的阿拉斯加洋流与南向的加利福尼亚洋流。

The North Pacific Current (sometimes referred to as the North Pacific Drift) is a slow warm water current that flows west-to-east between 40 and 50 degrees north in the Pacific Ocean. The current forms the southern part of the North Pacific Subpolar Gyre. The North Pacific Current is formed by the collision of the Kuroshio Current, running northward off the coast of Japan, and the Oyashio Current, which is a cold subarctic current that flows south and circulates counterclockwise along the western North Pacific Ocean. The North Pacific Current forms the northern part of the North Pacific Subtropical Gyre. In the eastern North Pacific near southern British Columbia, it splits into the southward California Current and the northward Alaska Current.
