The River Lune is a river of the United Kingdom, formed at Wath , North Yorkshire, at the confluence of Sandwath Beck and Weasdale Beck .
The river then passes the remnants of a Roman fort near Low Borrowbridge at the foot of Borrowdale, and flows through south Cumbria (its valley is known as Lonsdale), finally meeting the Irish Sea at Plover Scar near Lancaster, after a total journey of about 44 miles (70 km).
Bridges over the Lune include the Lune Millennium Bridge in Lancaster, through which it passes. Lancaster (and hence also Lancashire) is named after the Lune.
