Domenico Quaglio the Younger (1 January 1787 – 9 April 1837) was a German painter, engraver, stage designer, and architect.
He was the second son of Giuseppe Quaglio and part of the large Quaglio pedigree of Italian artists involved in architecture, indoor fresco decoration, and scenography for the court theatres.
He was taught perspective and scene painting by his father, and engraving by Mettenleiter and Karl Hess.
In 1819 he resigned his post as scene painter, and occupied himself only with architecture, for which he obtained subjects in the Netherlands, Italy, France, and England.
He engraved twelve plates of 'Architectural Monuments’‘, and lithographed thirty Remarkable German Buildings of the Middle Ages.
