Ynglinga saga (modern Icelandic pronunciation: [ˈiŋliŋka ˈsaːɣa]) is a Kings' saga, originally written in Old Norse by the Icelandic poet and historian Snorri Sturluson about 1225. It is the first section of his Heimskringla. It was first translated into English and published in 1844 by Samuel Laing.
Snorri Sturluson based his work on an earlier Ynglingatal which is attributed to the Norwegian 9th-century skald Þjóðólfr of Hvinir, and which also appears in Historia Norwegiae. It tells the most ancient part of the story of the House of Ynglings (Scylfings in Beowulf). Snorri described the descent of the kings of Norway from this royal house of Sweden.
