Felixstowe is an Edwardian seaside town and civil parish between the River Orwell and River Deben on the North Sea coast of Suffolk, England. The 2011 Census recorded the parish population as 23,689. It includes the Port of Felixstowe, which is the largest container port in the United Kingdom.
The nearby small town of Walton is often viewed as an extension of Felixstowe as the two towns are virtually side by side, though Walton was the original village. The quieter area nearer to the Deben River is often referred to as Old Felixstowe, there is though no formal classification of Old Felixstowe.
