Happisburgh (ⁱ/heɪz.brʌ/ HAYZ-bru) is a village and civil parish in the English county of Norfolk. It is situated off the B1159 coast road from Ingham to Bacton.

Happisburgh became a site of national archaeological importance in 2010 when flint tools over 800,000 years old were unearthed. This is the oldest evidence of human occupation anywhere in the UK. The other key paleolithic sites in the UK are Pakefield, Boxgrove, Swanscombe, Pontnewydd, Kents Cavern, Paviland, and Gough's Cave.

The civil parish has an area of 10.78 km² (4.16 sq mi), although this is declining due to cliff erosion. In the 2001 census, before the creation of Walcott parish, it had a population of 1,372 in 607 households. For the purposes of local government, the parish falls within the district of North Norfolk.

In 1086, The Normans built a church on the site of the current one. It was demolished and rebuilt in the 15th century. The tower of St Mary's church is an important landmark to mariners warning of the position of the treacherous nearby sandbanks. In 1940 a German bomber released a trapped bomb from its bays during its return to Germany and the shrapnel from the bomb can still be seen embedded in the aisle pillars of the church. The church's octagonal font, also of the 15th century, is carved with figures of lions and satyrs.
