Ynglinga saga 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 was an Icelandic historian, poet, and politician. He was elected twice as lawspeaker of the Icelandic parliament, the Althing. He is commonly thought to have authored or compiled portions of the Prose Edda, which is a major source for what is today known about Norse mythology and alliterative verse, and Heimskringla, a history of the Norse kings that begins with legendary material in Ynglinga saga and moves through to early medieval Scandinavian history. For stylistic and methodological reasons, Snorri is often taken to be the author of Egil's saga. He was assassinated in 1241 by men claiming to be agents of the King of Norway.
