Labaya (Labayu or Lib'ayu) was the ruler of Shechem and warlord in the central hill country of southern Canaan during the Amarna Period (c. 1350 BC). He lived contemporaneously with Pharaoh Akhenaten. Labaya is mentioned in several of the Amarna Letters (abbreviated "EA", for 'el Amarna'). He is the author of letters EA 252–54.
Labaya was active over the whole length of Samaria and slightly beyond, as he gave land to Habiru in the vicinity of Šakmu (Shechem) and he and his sons threatened such powerful towns as Jerusalem and Gazru (Gezer) to the south, and Megiddo to the north.
