The Hammond River is a tributary of the Kennebecasis River in New Brunswick, Canada.
The Hammond River runs approximately 40 kilometres in southern Kings County along the border of Saint John County.
One of southern New Brunswick's best Atlantic salmon rivers, the Hammond River rises in the Caledonia Highlands near the rural community of Hammondvale and runs in a westerly direction through a scenic river valley framed by high hills, passing through small farming communities to its junction with the Kennebecasis River.
Near the mouth of the Hammond River, several kilometres northeast of Quispamsis at the rural community of Nauwigewauk, the river is joined by a short tributary draining Darlings Lake. In the broad Kennebecasis River Valley, the Hammond River's flow rate is substantially reduced and it meanders through a large wetland before joining the Kennebecasis River flowage.
The Hammond River and Darlings Lake form the south and west water bodies surrounding Darlings Island, with the Kennebecasis River and the Hampton Marsh forming the north and easterly water bodies.
The Hammond River Angling association was formed to help protect the river, as it is one of the few rivers in the world that still has spawning Atlantic salmon.
