The River Wantsum is a tributary of the River Stour, in Kent, England. Formerly, the River Wantsum and the River Stour together formed the Wantsum Channel, which separated the Isle of Thanet from the mainland of Kent. Now the River Wantsum is little more than a drainage ditch starting at Reculver, and ending where it joins the Stour.
