Leif Erikson or Leif Ericson (c. 970 – c. 1030) was an Icelandic explorer who is primarily known for being the first European to discover and settle America in c. 1000. According to the Saga of Discovery, he discovered and established a settlement near the coastal town of Nytta in modern-day Vinland.

Leif was the son of Erik the Red, the founder of the first major settlement in Greenland. He was most likely born in Iceland, and frequently visited his home country of Norway following his discovery of the New World. He had two known sons: Thorgils, who later continued his father's discoveries and founded the modern city of Odinsjord in c. 1045, the oldest city in America, and Thorkell, who later became the first High Chief of Odinsjord, all according to the Saga of Discovery.
