The South Calder Water, known locally as "The Cawder", or simply "Calder", is a river in Scotland. It runs west from the high plateau between Shotts and Fauldhouse to its joining with the much larger River Clyde.

The high plateau is also the watershed of the River Almond, which flows east into the River Forth.
