Karl II, 8th Prince of Löwenstein-Wertheim-Rosenberg (German: Karl Fürst zu Löwenstein-Wertheim-Rosenberg (8 February 1904, Kleinheubach - 23 August 1990, Kleinheubach) was a German Roman Catholic nobleman. From 1948 to 1967 he was president of the Central Committee of German Catholics. Born as Prinz zu Löwenstein-Wertheim-Rosenberg, he inherited the title of 'Erbrpinz' on his father's death in 1952 and later became Fürst zu Löwenstein-Wertheim-Rosenberg.

The noble family Loewenstein-Wertheim goes back to the Wittelsbach Friedrich I., the Victorious, Elector of the Palatinate (1425-1476) and his son Ludwig . Karl comes from the marriage of Aloys Fürst zu Loewenstein-Wertheim-Rosenberg (1871-1952) and Karl was the third of the nine children of Aloys, 7th Prince of Löwenstein-Wertheim-Rosenberg and Josephine Countess Kinsky of Wchinitz and Tettau (1874-1946) and was the third of nine children. The House of Loewenstein-Wertheim is descended from Frederick I, Elector Palatine and his son Louis I, Count of Lowenstein. Karl studied at the Jesuit college of Stella Matutina in Feldkirch and later studied philosophy and jurisprudence in Innsbruck, Munich and Wurzburg. He graduated with a 'Dr. jur.' from Julius-Maximilians-Universität Würzburg in 1928 with a doctoral thesis on Erbverzicht und Abfindungsvertrag. He served as speaker for Catholic Youth and from 1933 to 1938 chairman of the 'Verband der Wissenschaftlichen Katholischen Studentenvereine Unitas' (the Unitas Association of Catholic Scientific Student Societies), until it was disbanded in 1938 by the Nazi regime.
