The River Nene (/ˈnɛn/ or /ˈniːn/: see below) is a river in the east of England that rises from three sources in Northamptonshire. The tidal river forms the border between Cambridgeshire and Norfolk for about 3.7 miles (6.0 km). It is the tenth-longest river in the United Kingdom, and is navigable for 88 miles (142 km), from Northampton to The Wash.

The pronunciation of the river's name varies by locality. In Northamptonshire, it is usually /ˈnɛn/, and around Peterborough, it is usually /ˈniːn/. The spelling was "Nenn", as seen in Cole-Roper's 1810 engraving, or "Nyn" until the beginning of the 20th century, and the point at which the pronunciation changes has been moving further inland for many years; the current edition of the Imray "Map Of The River Nene" suggests that it is now Thrapston.
