The River Ise is a river in Northamptonshire, England and a tributary of the River Nene.
The river rises in the very field that hosted the Battle of Naseby at the north-western tip of Northamptonshire. Flowing east past Desborough and the Eleanor cross at Geddington, through the grounds of Rushton Hall it then turns south and passes Kettering, through Wicksteed Park, past Barton Seagrave and Burton Latimer before joining the Nene just south of Wellingborough.
Fishing on The Ise
The Ise contains many varieties of coarse and game fish, including roach, perch, barbel and chub. It is also the only watercourse within Northamptonshire to contain grayling (thymallus thymallus).
