Yngve Alriksson King in Uppsala
- Born: Abt 466, Sweden

King Yngve Alreksson is Eric & Evan Obrock's 49th great-grandfather. He was King of Uppsala, Sweden.
According to Ynglingatal, Historia Norwegiae and Ynglinga saga, Yngvi and Alf were the sons of Alrik. Yngvi was an accomplished king: a great warrior who always won his battles, the master of all exercises, generous, happy and sociable. He was both loved and famous. Alf was unsociable and harsh and stayed at home instead of pillaging in other countries. His mother was Dageid, the daughter of king Dag the Great from whom is descended the Dagling family.
Alf was married to Bera who was happy and alert and a very lovable woman. One day in the autumn, Yngvi returned to Uppsala from a very successful viking expedition which had rendered him famous. He used to spend time at the drinking table until late in the night, like Bera, and they found it pleasant to talk to each other. Alf, however, preferred to go to bed early and he started to tell her to go to bed early as well so that she did not wake him. Then Bera used to answer that Yngvi was much better for a woman than Alf, an answer that was getting on Alf's nerves. One evening, the jealous Alf entered the hall and saw Yngvi and Bera converse on the high seat. Yngvi had a short sword in his lap and the other guests were too drunk to see that Alf had arrived. From under his cloak Alf drew a sword and pierced Yngvi. Yngvi, mortally wounded, got up, drew his own short sword and slew Alf.
They were buried in two mounds on the Fyrisvellir (Fyris Wolds). Alf was succeeded by his son Hugleik.
I tell you of a horrid thing, A deed of dreadful note I sing -- How by false Bera, wicked queen, The murderous brother-hands were seen Each raised against a brother's life; How wretched Alf with bloody knife Gored Yngve's heart, and Yngve's blade Alf on the bloody threshold laid. Can men resist Fate's iron laws? They slew each other without cause
In the Hervarar saga and the saga of Orvar-Odd, Yngvi was the father of Ingeborg, the princess who was in love with the Swedish hero Hjalmar.
