Thorvald Eiriksson (Old Norse: Þórvaldr Eiríksson [ˈθoːrˌwɑldz̠ ˈɛiˌriːksˌson]; Modern Icelandic: Þorvaldur Eiríksson [ˈθɔrˌvaltʏr ˈeiːˌriksˌsɔːn]) was the son of Erik the Red and brother of Leif Erikson. The only Medieval Period source material available regarding Thorvald Eiriksson are the two Vinland sagas; the Greenland Saga and the Saga of Erik the Red. Although differing in various detail, according to both sagas Thorvald was part of an expedition for the exploration of Vinland and became the first European to die in North America.
