Count Erik Jönsson Dahlbergh (10 October 1625 – 16 January 1703) was a Swedish military engineer, Governor-general and Field marshal.
He was born of peasant stock but he eventually rose to the level of nobility through his military competence.
As an architect and draftsman, he was renowned for fortification works.
His collection of engravings Suecia Antiqua et Hodierna is a remarkable work of topographical research.
