The Sydenham River is a river in Kent County and Middlesex County in southwestern Ontario, Canada flows southwest from its source west of London, Ontario and empties into Lake Saint Clair. The length of the river is 100 kilometres and it drains a watershed of approximately 2,700 square kilometres. The river flows through the towns of Strathroy and Wallaceburg.
Because this river flows through a large agricultural area, its waters collect silt and fertilizer runoff. In spite of this, the river provides habitat for 80 fish species and 34 species of freshwater mussels; these include:
five mussel species considered as "endangered" nationally
Unusual concretions, composed of calcite, can be found near this river. These are known as "kettles" because they resemble the bottom of a large kettle.
There is also a second smaller Sydenham River in Grey County, Ontario which empties into Owen Sound harbour.

The SydenhamRiver in southwestern Ontario is the only major watershed which lies completely in the Carolinian Life Zone and is relatively undisturbed by industrial development.
