The River Waveney is a river which forms the boundary between Suffolk and Norfolk, England, for much of its length within The Broads. The earliest attestation of the name is from 1275, Wahenhe, from *wagen + ea, meaning the river by a quagmire.

The Broads is a network of mostly navigable rivers and lakes in the English counties of Norfolk and Suffolk. Although the terms "Norfolk Broads" and "Suffolk Broads" are correctly used to identify specific areas within the two counties respectively, the whole area is frequently referred to as the Norfolk Broads.
