A cupule is a small structure shaped like a cup, including:

  • In archeology, rock cupules are circular man-made hollows on the surface of a large rock or a rock slab
    • On a smaller artifact they are called a cupstone.
  • In botany: the base of an acorn, see calybium and cupule.
  • In entomology, a sucker on the feet of some flies.
