The superior pancreaticoduodenal artery is an artery that supplies blood to the duodenum and pancreas. It is a branch of the gastroduodenal artery, which comes from the celiac trunk. The term superior in its name distinguishes the superior pancreaticoduodenal artery from the inferior pancreaticoduodenal artery, which a branch of the superior mesenteric artery. These arteries, together with the pancreatic branches of the splenic artery, form connections or anastomoses with one another, allowing blood to perfuse the pancreas and duodenum through multiple channels.

The artery splits into two branches:

the anterior superior pancreaticoduodenal artery supplies the anterior margins of the duodenum and pancreas
the posterior superior pancreaticoduodenal artery supplies the posterior margins of these organs
