The River Tove is a river in England, a tributary of the River Great Ouse. Rising in Northamptonshire about a mile north of Greatworth, it flows for about 15 miles (24 km) north and east of the town of Towcester (meaning 'camp on the Tove') near Bury Mount before meeting the Ouse south-east of Cosgrove just north of Milton Keynes. Its final 5 miles (8 km) form part of the border between Northamptonshire and Buckinghamshire, running alongside the Grand Union Canal.
