The celiac plexus (plural: plexuses) is an autonomic nerve plexus and ganglia in the upper abdomen. It is the largest major autonomic plexus.

location: the ganglion and plexus lie close to the celiac trunk
origin:
- preganglionic sympathetic fibers via the greater and lesser splanchnic nerves
- preganglionic parasympathetic fibers from the vagus nerves
branches and supply: gives origin to a complex network of small branches which follow the celiac artery branches and extends inferiorly to the superior mesenteric plexus and laterally to the aorticorenal plexus
- supplies the distal esophagus, stomach, spleen, liver (via the hepatic plexus), gallbladder, pancreas and proximal duodenum
relations:
- anterior: stomach, lesser sac, IVC (right ganglion) and splenic artery origin (left ganglion)
- posterior: diaphragmatic crura and the abdominal aorta
- lateral: adrenal glands
