南萨斯喀彻温河(英语：South Saskatchewan River、法语：rivière Saskatchewan Sud)是加拿大一条主要河流，从亚伯达省流到萨斯喀彻温省。

于20世纪上半叶，南方萨斯喀彻温河将在冬季完全冻结，造成壮观的水静止流动景象，但也为萨斯卡通和梅迪辛哈特带来的水患。至少有一条在萨斯卡通的桥梁被带冰的河水冲毁。1960年代建造的加德纳大坝解决了水患，但因流量减少而导致河流中出现了许多沙洲。

它源自弓河，流经1392公里的地方到达萨斯喀彻温河交汇处，有280米的落差。流域面积为146,100平方公里，其中1,800平方公里位于美国蒙大拿州，其余位于亚伯达省和萨斯喀彻温省

The South Saskatchewan River is a major river in Canada that flows through the provinces of Alberta and Saskatchewan.

For the first half of the 20th century, the South Saskatchewan would completely freeze over during winter, creating spectacular ice breaks and dangerous conditions in Saskatoon, Medicine Hat and elsewhere. At least one bridge in Saskatoon was destroyed by ice carried by the river. The construction of the Gardiner Dam in the 1960s, however, lessened the power of the river by diverting a substantial portion of the South Saskatchewan's natural flow into the Qu'Appelle River. By the 1980s many permanent sandbars had formed due to the lowering of the level of the river.
