Ecgþēow (pronounced [ˈedʒðeːow]), Edgetho (Proto-Norse *Agiþewaz), or Ecgtheow is a character in the Anglo-Saxon epic Beowulf. He is not mentioned outside the Bēowulf manuscript, and it is not known whether he was based on a real person. He belonged to a probably Swedish family (an ätt, see Norse clans) called the Waegmundings. He married the daughter of Hreðel, king of the Geats, and was the father of Bēowulf.
His name could be read as eċġ + þēow, "edge-servant" (that is, sword-thane); alternatively, if his name was a compound of the ancient bahuvrihi type as were many other Germanic heroic names, it would indicate proficiency with the sword, meaning literally, "whose servant is the sword".
