Nikolaus Friedrich von Thouret (born Ludwigsburg, 2 June 1767; died Stuttgart, 17 January 1845) was a German architect and designer.

An early architectural project was the Gothic Revival church of Hohenheim (1797; re-erected 1803 at Monrepos, Ludwigsburg; ruin since the 1940s.

With the assistance of Goethe, whom he met in Stuttgart in 1797, Thouret was commissioned to design the décor of the Schloss in Weimar and to renovate the court theatre there (1798–1800).

On his return to Stuttgart, Thouret was appointed court architect to Frederick II, Duke of Württemberg (1754–1816), in 1799.

Instead, he continued to be given design commissions and was involved in almost all the foremost architectural projects undertaken in Stuttgart to the 1830s (e.g., Katharinenhospital, 1827; Hoftheater, 1833).
