The River Ouse (pronounced "ooze") in North Yorkshire, England flows through York and Selby. It joins the River Trent at Faxfleet, to form the River Humber.

Its system of tributaries (which includes the Derwent, Aire, Don, Wharfe, Rother, Nidd, Swale, Ure, and Foss) drains a large upland area of Northern England, including much of the Yorkshire Dales and North York Moors. The Ouse valley is a wide, flat plain; heavy rainfall in the river's catchment area can bring severe flooding to nearby settlements. In recent years both York and Selby, and villages in between, have been very badly hit.
