Georg Moller (21 January 1784 – 13 March 1852) was an architect and a town planner who worked in the South of Germany, mostly in the region today known as Hessen.

During the years 1807–1809 Moller took a study trip to Rome where he gained crucial insight from members of the Roman colony of German artists.

Furthermore, he designed the Staatstheater Mainz, which created a stir because of its semicircular facade, and the Stadtschloss Wiesbaden of the Dukes of Nassau, today the seat of the Landtag of Hesse.

Only two of Georg Moller's major works survived the second world war without damages: the grand-ducal mausoleum at the Rosenhöhe [de] and the Ludwigsmonument on the Luisenplatz, both of them in Darmstadt.

Moller is considered, along with Karl Friedrich Schinkel and Leo von Klenze, to be one of the most important German architects working in the Greek Revival and Romanticist styles.

His book Denkmähler der Deutschen Baukunst ("Milestones in German architecture"; 1815–1851)[1] covered buildings from Lorsch (founded 764) to Oppenheim (14th century).
