Levin Rauch de Nyek (1819 - 1890) was a politician from the Kingdom of Hungary in the late 19th century, the viceroy of Croatia-Slavonia for four years (1867-1871).
Rauch was a member of the unionist party that advocated an integration of Croatia and Hungary. After the Revolutions of 1848, Croatia became a Habsburg crown territory separate from Hungary, but when the Austrian-Hungarian Ausgleich was signed, Austria-Hungary was created and Rauch was appointed as the acting ban of Croatia on June 27, 1867. By this, the Croatian autonomy within the Hungarian kingdom was automatically abolished.
During this time a new Croatian-Hungarian Settlement (Nagodba) was negotiated and put in effect by which Croatia reinstated some of its earlier autonomy, but also lost some other rights. Rauch was made the official ban on December 8, 1868 and remained in office until January 26, 1871.
