The River Cam is the main river flowing through Cambridge in eastern England. After leaving Cambridge, it flows north and east into the Great Ouse to the south of Ely at Pope's Corner. The Great Ouse connects the Cam to the North Sea at King's Lynn: The total distance from Cambridge to the sea is about 40 mi (64 km) and is navigable for punts, small boats, and rowing craft. The Great Ouse also connects to England's canal system via the Middle Level Navigations and the River Nene. In total, the Cam runs for around 69 kilometres (43 mi) from its furthest source (near Debden in Essex) to its confluence with the Great Ouse.
The original name of the river was the Granta and (unusually) its present name derives from the city of Cambridge (Old English: Grantebrycge) rather than the other way around: After the city's present name developed in Middle English, the river's name was backformed to match. This was not universally applied, however, and the upper stretch of the river continues to be informally known as the Granta. It has been said that the river is the "Granta" above the Silver Street Bridge (in Cambridge) and the "Cam" below it. The Rhee tributary is also formally known as the Cam, and the Granta has a tributary on its upper stretch also known as the Granta.
The Cam has no connection with the much smaller River Cam in Gloucestershire.
