The ampulla of Vater, hepatopancreatic ampulla or hepatopancreatic duct is the common duct that is usually formed by a union of the common bile duct and the pancreatic duct within the wall of the duodenum. This common duct usually features a dilation ("ampulla"). The common duct then opens medially into the descending part of the duodenum at the major duodenal papilla. The common duct usually measures 2-10mm in length.^[1]

The ampulla of Vater is an important landmark halfway along the second part of the duodenum marking the transition from foregut to midgut.^{[citation needed]}
