Albert Joseph Gasteiger (known in Persian as Gāstager Khan; 28 March 1823–5 July 1890), was an Austrian nobleman and engineering officer. Born in Innsbruck, he became an instructor at the Dar ol-Fonun in Qajar Iran, as well as the manager of all civilian and military buildings at the behest of Iran's government from 1860 to 1888.
