Ferdinand Joachimsthal (born March 9, 1818 in Goldberg i. Silesia , † April 5, 1861 in Breslau ) was a German mathematician.

Joachimsthal went to high school in Liegnitz , where Ernst Eduard Kummer was his mathematics teacher. From 1836 he studied mathematics at the University of Berlin under Dirichlet and Jakob Steiner , from 1838 at the University of Königsberg under Carl Gustav Jacobi and Friedrich Wilhelm Bessel and at the University of Halle , where he received his doctorate in 1840. From 1844 he taught at the Royal Realschule in Berlin. In 1845 he completed his habilitation in Berlin (De curvis algebraicis) and then taught at the University of Berlin and from 1847 he was at the French grammar school, where he became a professor in 1852. In 1850 he completed his habilitation a second time in Breslau. In 1853 he became professor in Halle and in 1855 as successor to Kummer professor at the University of Breslau .

He dealt with differential geometry and analytical geometry, especially of surfaces (for example normals on quadrics ) and was known for the high quality of his lectures, two of which were published posthumously as books.
