Heinrich Ernst Schirmer (27 August 1814 - 6 December 1887) was German-born architect most noted for his work in Norway.
Schirmer worked in Norway from 1838 to 1883 and put his mark on a number of public buildings.
He contributed significantly to the introduction of the so-called Swiss architectural style in Norway, based partly on Italian villa style, Gothic Revival, and neoclassicism.
