The Sydenham River is a river in Chatham-Kent, Lambton County and Middlesex County in southwestern Ontario, Canada, flowing southwest from its source west of London, Ontario and emptying into Lake Saint Clair. The length of the river is 165 kilometres (103 mi) and it drains a watershed of approximately 2,700 square kilometres (1,000 mi2), making it one of the largest river flowing into the St.Clair on the Canadian side. The river flows through the towns of Strathroy and Wallaceburg. It was named after Lord Sydenham, governor of Canada from 1839 to 1841.
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.
The river has been identified as a key biodiversity area.
