A bile canaliculus (plural: bile canaliculi; also called bile capillaries) is a thin tube that collects bile secreted by hepatocytes. The bile canaliculi empty into a series of progressively larger bile ductules and ducts, which eventually become common hepatic duct. The bile canaliculi empty directly into the canals of Hering.

The bases of adjacent hepatocytes surround a dilated space known as the bile canaliculi (s. canaliculus). The canaliculi mark the beginning of the intrahepatic biliary system and serve as conduits for bile as it is secreted from the basal surface of the hepatocytes.
