Kenninghall is a village and civil parish in Norfolk, England, with an area of 5.73 sq mi (14.8 km2) and a population of 950 at the 2011 census.

It has been claimed that the name Kenninghall comes from the Saxon word Cyning (king) and Halla (palace), but this is debated, with other writers deriving it from the personal name "Cyna" and the Old English "hala", a clearing in the woods.

In the reign of Henry VIII, the estate was granted to Thomas Howard, 2nd Duke of Norfolk, who abandoned the ruins of older structures within an ancient moat and erected a new East Hall to the north of the Saxon site.

The third Duke spent lavishly to build an entirely new, unfortified, palace of more than 70 rooms, richly furnished with tapestries and thousands of ounces of silver and gilt plate.

Between 1727 and 1760, George II issued a charter declaring the inhabitants of Kenninghall exempt from serving in juries outside the parish, and from tolls at fairs across the kingdom.
