The River Freshney is a river in the English county of North East Lincolnshire. The town of Grimsby stands on its banks. It rises from at least four springs on the edge of the Lincolnshire Wolds, although local folklore and oral tradition has it springing from Welbeck Hill. Originally it entered the tidal River Humber at Pyewipe, north west of Grimsby, but has been re-routed and now supplies Grimsby Docks.There was an existing haven within the borough of Grimsby but this suffered greatly with silting problems so in 1669 landowners agreed to the diversion of the Freshney through the town to the haven to provide fresh water and improve the flow. It is believed the work was completed in the very early 18th century.
