Loddon is a town and civil parish in Norfolk, England, about 12 miles (19 km) south-east of Norwich. The town lies on the River Chet, a tributary of the River Yare within The Broads. The name "Loddon" is thought to mean muddy river in Celtic in reference to the Chet.

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.
