The Jock River, known locally as the Mighty Jock, is a river in Ottawa and Lanark County in Eastern Ontario, Canada. It is in the Saint Lawrence River drainage basin and is a left tributary of the Rideau River. The river is named after Jacques, a French man who drowned in it in the early 19th century, and it was once known as the Goodwood River. The River is supported by a community-volunteer organization known as the Friends of the Jock River.
