Thorir Rögnvaldarson (also Tore Teiande, nicknamed the Silent, 872 - 940) was a viking leader of the 9th century son of Rognvald Eysteinsson, jarl of Møre, Norway and brother of Hrolf Ganger (Rollo), first Viking caudillo that would initiate a a race that would govern the Duchy of Normandy and Ivar Rögnvaldsson. In 892, Thorir assumed his role as jarl of Møre after the death of his father.
Thorir was married to Ålov, daughter of Harald I of Norway, and had two daughters, Bergljot (n.914) who married Lade Sigurd Håkonsson's jarl, Vigdis (n.918), and a male named Jorund (b. 916) He is also charged with the paternity of Thorbard av Møre.
Two sons of King Harald I of Norway, Halvdan Hålegg and Gudrød Ljome (Gudrod the Shining), killed Thorir's father by harassing him in his own house and setting him on fire. Gudrød took possession of the lands of Rögnvald while Hálfdan sailed west towards the Orkneys to overthrow Torf-Einarr. King Harald, apparently horrified by the actions of his sons, dispossessed Gudrød and restored the possessions of Rögnvald to Thorir, assuming his role as jarl de Møre after the death of his father.
