Sleitu-Björn Hróarsson (born c. 890 - date of death unknown) was a viking chief and the first to found a settlement in Skagafjörður, Iceland in the ninth century.Íslendingabók og Landnámabók (1968), Jakob Benediktsson, 1907-., (1 volume in 2 parts. Reykjavík, Iceland: Íslenzka Fornritafélag, 1968), FHL book 949.12 H2bj., vol. 1, pt. 1-2, p. 143, 158, 159, 181, 180, 197, 105; vol. 1, pt. 2, p. 236, 237, 240, 205. Source continued: Table 10, #117. It was one of the largest settlements of this period, spanning from the river ( in the Landnámabók) through half of Viðvíkursveit, Hjaltadalur, Kolbeinsdalur, and Óslandshlíð, and part of Höfðaströnd and Deildardalur. Later on, three more settlers joined him: Öndóttur, Kolbeinn Sigmundarson, and Hjalti Þórðarson. Sleitu-Björn divided part of the settlement and his estate was founded in Sleitustaðir.Islenzkar æviskrár frá landnámstímum til ársloka 1940 (1948-1976), Páll Eggert Ólason, Jón Guðnason, and Ólafur Þ.

There is a historical controversy in which various researchers believe that Sleitu-Björn is the same person as Sléttu-Björn,Landnámabók, Parte II, Pag. 6 Asentamientos de Steinolf, Slettu-Bjorn, Olaf Belg, y Gisl Skeid-neb a colonist who settled in Saurbær, Dalasýsla who abandoned his settlement in Skagafjörður to relocate to the west. However, others maintain, either based on his list of descendants and the sagas, that these are two different people. Sléttu-Björn also appears in the Gull-Þóris saga.Þorskfirðinga saga (filmed 1948), Valdimar Ásmundsson, (Salt Lake City, Utah : Filmet av the Genealogical Society of Utah, 1948), FHL 73,227 Item 10., pt. 2, p. 3, 4.Aarbøger for nordisk oldkyndighet og historie (1908), Kongelige Nordiske oldskriftselskab (Denmark), p. 181.
