Nikolaus Gromann (c. 1500 – 29 November 1566) was an architect of the German Renaissance who served at the court of John Frederick I, Elector of Saxony. He also worked for John Frederick's descendants residing in the cities of Weimar, Gotha and Altenburg, thus spending more than 30 years in the service of the House of Wettin.
