Snettisham is a village and civil parish in the English county of Norfolk. It is located near the west coast of Norfolk, some 5 miles south of the seaside resort of Hunstanton, 9 miles north of the town of King's Lynn and 45 miles northwest of the city of Norwich.
The village's name means 'Snaet's/Sneti's homestead/village'.
The civil parish has an area of 28.03 km² and in the 2001 census had a population of 2374 in 1097 households. For the purposes of local government, the parish falls within the district of King's Lynn and West Norfolk. The Civil Parish population had increased to 2,570 at the 2011 Census.
Snettisham RSPB reserve, on the coast of The Wash some 2 miles to the west of Snettisham village, is a nature reserve in the care of the Royal Society for the Protection of Birds. It consists of bird lagoons and bird observation hides, including a rotary hide.
The Snettisham coast around the reserve is often said to be "where Norfolk stares at Lincolnshire". This is because, unlike much of Norfolk's coast where the sea stretches to the horizon, Snettisham looks across the square-mouthed estuary of The Wash at the county of Lincolnshire, only 15 miles away.
