The Fairhair dynasty was a family of kings founded by Harald I of Norway which united and ruled Norway with few interruptions from the latter half of the 9th century. In the traditional view, this lasted until 1387, however, many modern scholars view this rule as lasting only three generations, ending with Harald Greycloak in the late 10th century. The moniker "Fairhair dynasty" is a retrospective construction: in their lifetime what little traces there are refer to them consistently as "Ynglings".

The Ynglings were a dynasty of kings, first in Sweden and later in Norway, primarily attested through the poem Ynglingatal. The dynasty also appears as Scylfings in Beowulf. When Beowulf and Ynglingatal were composed sometime in the eighth to tenth centuries, the respective scop and skald (poet) expected his audience to have a great deal of background information about these kings, which is shown in the allusiveness of the references.
