Ludwig Christian Wiener (7 December 1826 Darmstadt – 31 July 1896 Karlsruhe) was a German mathematician who specialized in descriptive geometry. Wiener was also a physicist and philosopher. In 1863, he was the first person to identify qualitatively the internal molecular cause of Brownian motion.

Wiener was the son of a judge and studied architecture and engineering in Giessen. After the state examination in 1848, he became a teacher at the "Höhere Gewerbeschule" in Darmstadt, today the Technische Universität Darmstadt.^[1]

The mathematician Hermann Wiener was his son.
