A striated duct is a gland duct which connects an intercalated duct to an interlobular duct. It is characterized by the basal infoldings of its plasma membrane, characteristic of ion-pumping activity by the numerous mitochondria.^{[1] [2]} Along with the intercalated ducts, they function to modify salivary fluid by secreting HCO₃^- and K⁺ and reabsorbing Na⁺ and Cl^- using the Na-K pump and the Cl-HCO₃ pump.

Their epithelium can be simple cuboidal or simple columnar.^[3]

Striated ducts are part of the intralobular ducts.

They are found in the submandibular gland^[4][5] and the parotid gland.^[6]

They are not present in pancreas.
