The River Waver is a river in Cumbria, England. The river rises at Wavergillhead (as Townthwaite Beck). It is fed by the northwards flowing Thornthwaite Beck and Pow Gill either side of Bolton Wood Lane. The "Little Waver", rising at Catlands Hill, joins at Waterside near Woodrow. The river then takes a northward course via Waverton and Waverbridge, before turning sharply westwards at Abbey Town. The river then goes north, running into Moricambe Bay, an inlet of the Solway Firth.
