Merneferre Ay (also spelled Aya or Eje, sometimes known as Ay I) was an ancient Egyptian pharaoh of the mid 13th Dynasty. The longest reigning pharaoh of the 13th Dynasty, he ruled a likely fragmented Egypt for over 23 years in the early to mid 17th century BC. A pyramidion bearing his name shows that he possibly completed a pyramid, probably located in the necropolis of Memphis.
