line of succession to the Norwegian throne is the list of people who may become King or Queen of Norway. 
Since 1990, Norwegian law identifies the eldest child of a Norwegian monarch the royal heir. The first-born child follows his or her parent on the throne.
This is known as full or equal  primogeniture.
In 2011, the current order of
succession is clear.
