The Kingittorsuaq Runestone (old spelling: Kingigtorssuaq), listed as GR 1 in the Rundata catalog, is a runestone that was found on Kingittorsuaq Island, an island in the Upernavik Archipelago in northwestern Greenland.
The Kingittorsuaq Runestone was found in 1824 in a group of three cairns that formed an equilateral triangle on top of the mountain on Kingittorsuaq Island in the south-central part of the Upernavik Archipelago. The stone is now located at the National Museum of Denmark in Copenhagen.
The stone has been dated to the Middle Ages. The Catholic Encyclopedia states the date as April 25, 1135. William Thalbitzer dates the stone to 1314 using pentadic numerals. Others have dated the stone between 1250 and 1333. However, as the historian Finn Gad has pointed out, the date given on the stone can be interpreted in various ways. As such, it cannot, as previously thought, be taken as evidence for the three hunters named on the stone in this region.
Latin transliteration of the text on the runestone:
- el=likr * sikuaþs : so=n:r * ok * baan=ne : torta=r son : ok enriþi * os son : laukardak*in : fyrir * gakndag hloþu * ua=rda te * ok rydu : (followed by six unknown characters) 
Old Norse transcription:
- Erlingr Sigvatssonr ok Bjarni Þórðarson og Eindriði Oddsson laugardaginn fyrir gangdag hlóðu varða þessa ok ryðu...
- Erlingur the son of Sigvat and Bjarni Þorðar's son and Eindriði Oddr's son, the washingday (Saturday) before Rogation Day, raised this mound and rode...
The six runes following the translated text are undeciphered, though they do have very close single-character components. The first two and final runes appear to have two components, a Sowilō (ᛋ) with a Mannaz (ᛘ) and/or Algiz (ᛉ) on the top and bottom. The following three runes appear also to have the top and bottom Mannaz or Algiz, just with a Jēran (ᛄ) instead.
