Seaton Valley is a civil parish at the south eastern corner of Northumberland, and northern North Tyneside, consisting of five villages lying between Cramlington, Blyth and Whitley Bay. The largest village is Seaton Delaval, while Seaton Sluice is on the coast; the other three are Seghill, New Hartley, and Seaton Burn (which is in North Tyneside)

It takes its name from the stream Seaton Burn, a small river which flows through the area.

It was preceded by the Seaton Valley Urban District which existed until 1974, but has different boundaries; the urban district contained Cramlington, but did not contain Seaton Sluice which was then part of Borough of Whitley Bay.

The community council consists of nine elected members:

• Susan Dungworth (chair)
• Graham Eastwood (vice chair)
• David Ferguson
• Jill Henderson
• Les Bowman
• Eva Coulson
• Ann Stanners
• Sue Bowman
• Eve Chicken
