Burnham Overy is a civil parish on the north coast of Norfolk, England. In modern times a distinction is often made between the two settlements of Burnham Overy Town, the original village adjacent to the parish church and now reduced to a handful of houses, and Burnham Overy Staithe, a rather larger hamlet about 1 mile (2 km) away and next to the creek-side harbour.
Burnham Overy lies between the larger village of Burnham Market, less than 1 mile (2 km) to the west, and Holkham, some 3 miles (5 km) to the east. Burnham Thorpe, the birthplace of Horatio Nelson, lies 1 mile (2 km) to the south-east. According to various letters and documents, Nelson learned to row and sail a dinghy at Burnham Overy Staithe, at the age of 10, two years before joining the Navy. The larger town of King’s Lynn is 20 miles (30 km) to the south-west, whilst the city of Norwich is 30 miles (50 km) to the south-east.
The civil parish has an area of 8.92 km2 and in the 2001 census had a population of 311 in 167 households. For the purposes of local government, the parish falls within the district of King’s Lynn and West Norfolk.
