In anatomy, the splenic vein (in the past called the lienal vein) is the blood vessel that drains blood from the spleen.

It joins with the superior mesenteric vein, to form the hepatic portal vein and follows a course superior to the pancreas, along side of the similarly named artery, the splenic artery.

It collects branches from the stomach and pancreas and most notably from the large intestine, which is drained by the inferior mesenteric vein and joins with splenic vein shortly before it forms the portal vein.
