Egill's Saga or Egil's saga ( ; ) is an Icelandic saga (family saga) on the lives of the clan of Egill Skallagrímsson (Anglicised as Egill Skallagrimsson), an Icelandic farmer, viking and skald. The saga spans the years c. 850–1000 and traces the family's history from Egill's grandfather to his offspring.

Its oldest manuscript (a fragment) dates back to c. 1250 AD. The saga comprises the sole source of information on the exploits of Egill, whose life is not historically recorded. Stylistic and other similarities between Egill's Saga and Heimskringla have led many scholars to believe that they were the work of the same author, Snorri Sturluson. The work is generally referred to as Egla by Icelandic scholars.

The saga begins in Norway around 850, with the life of Egill's grandfather Ulf (Úlfr) aka Kveldulf or "Evening Wolf", and his two sons Thorolf (Þórólfr) and Skallagrim (Skalla-Grímr). Strife with the royal house drive the family out of the country, and they settle in Iceland. The brothers Egill and Thorolf Skallagrimsson are born. They have a tenuous tenure in Norway, but Egill is outlawed and they roam Scandinavia and serve the king of England. Egill tries to reclaim property back in Norway (as his wife's inheritance), but this is blocked, and Egill develops a personal vendetta against the King.

There are also vivid descriptions of his other fights and friendships, his relationship with his family (highlighted by his jealousy, as well as fondness for his older brother Thorolf), his old age, and the fate of his own son Thorstein (Þorsteinn, who was baptized once Roman Catholicism came to Iceland) and his children, who had many children of their own. The saga ends around the year 1000 and spans many generations.

Kveldulf's lineage

Ulf (Kveldulf) had Hallbjorn Halftroll as his maternal uncle, and was known for his surpassing size and strength. He had accrued land and property from viking raids, and was a man of wisdom. He earned the nickname Kveldulf (Kveldúlfr, "Evening Wolf") because of his erratic temper at nightfall, and reputation for manifesting the so-called "shape-shifter" (hamrammr) abilities, explained in later chapters to be comparable (or equatable) with berserk fury. Extreme personal traits like these are manifested by his son Skallagrim
