Pi Orionis (π Ori, π Orionis) is a group of fairly widely scattered stars in the constellation Orion that constitute the asterism Orion's Shield or Orion's Bow.[1]

They form an exception to the general rule that stars that share the same Bayer designation are close together: π1 is nearly 9° north of π6 (Tau Eridani is an even more noteworthy example of this).

All of them were member of asterism 參旗 (Shēn Qí), Banner of Three Stars, Net mansion.[2]
