The '''celiac plexus''', also known as the '''solar plexus''' because of its radiating nerve fibers,<ref>{{cite web|url=http://www.merriam-webster.com/dictionary/solar+plexus.|title=Definition of SOLAR PLEXUS|website=www.merriam-webster.com}}</ref> is a [[nerve plexus|complex network of nerves]] located in the [[abdomen]], near where the [[celiac trunk]], [[superior mesenteric artery]], and [[renal arteries]] branch from the [[abdominal aorta]]. It is behind the [[stomach]] and the [[omental bursa]], and in front of the [[crus of the diaphragm|crura]] of the [[diaphragm (anatomy)|diaphragm]], on the level of the first [[lumbar vertebra]].

The plexus is formed in part by the greater and lesser [[splanchnic nerves]] of both sides, and fibers from the [[anterior vagal trunk|anterior]] and [[posterior vagal trunk|posterior vagal trunks]].

The celiac plexus proper consists of the [[celiac ganglia]] with a network of interconnecting fibers.  The [[aorticorenal ganglia]] are often considered to be part of the celiac ganglia, and thus, part of the plexus.
