'''Pi Orionis''' (π Ori, π Orionis) is a group of fairly widely scattered [[star]]s in the [[constellation]] [[Orion (constellation)|Orion]] that constitute the [[asterism (astronomy)|asterism]] '''Orion's Shield''' or '''Orion's Bow'''.<ref name=RBR-Orion>astrofoto.org, [http://www.astrofoto.org/book/export/html/92 "Orion: The Hunter"] {{webarchive|url=https://web.archive.org/web/20130610090338/http://www.astrofoto.org/book/export/html/92 |date=2013-06-10 }}, Roland B.

They form an exception to the general rule that stars that share the same [[Bayer designation]] are close together: π<sup>1</sup> is nearly 9° north of π<sup>6</sup> ([[Tau Eridani]] is an even more noteworthy example of this).
