Newcastle's river (4)

I believe the answer is:

tyne

'newcastle's river' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for tyne that I've seen before include "River of NE England" , "River of Northumberland" , "Banker" , "River running through Newcastle" , "North of England river" .)

I've seen this clue in The Wall Street Journal, the Newsday and The Guardian.
