Jacob Fortling (23 December 1711 – 16 July 1761) was a German-Danish sculptor, architect and industrialist, described as one of the most industrious people in the Denmark of his day. He came to Denmark at age 18 and embarked on a successful career, first as a sculptor and later also as an architect. He was also engaged in the production of building materials, owning several quarries in Norway. Just outside Copenhagen, on Amager's east coast, he founded Kastrup Værk, a large industrial facility combining a lime plant, a brickyard and a pottery.
