本格拉寒流是南大西洋东海岸沿南非和纳米比亚西海岸从南向北流动的寒冷的水流，最终汇入南赤道暖流。

本格拉寒流构成南大西洋亚热带洋流的东部。水源包括印度洋和南大西洋亚热带温跃层海水；高盐分、低含氧的热带大西洋海水；和寒冷、较淡的深海水。本格拉寒流宽约2-300千米，向北流动时还进一步变宽。其西部界限不甚清晰，有许多季节性临时漩流。

The Benguela Current /bɛŋˈɡweɪlə/ is the broad, northward flowing ocean current that forms the eastern portion of the South Atlantic Ocean gyre. The current extends from roughly Cape Point in the south, to the position of the Angola-Benguela front in the north, at around 16°S. The current is driven by the prevailing south easterly trade winds. Inshore of the Benguela Current proper, the south easterly winds drive coastal upwelling, forming the Benguela Upwelling System. The cold, nutrient rich waters that upwell from around 200–300 m depth in turn fuel high rates of phytoplankton growth, and sustain the productive Benguela ecosystem.
