Margrave Wilhelm of Baden (8 April 1792 in Karlsruhe – 11 October 1859 in Karlsruhe) was the second son of Karl Friedrich, Grand Duke of Baden and his second wife, Luise Karoline, Baroness Geyer von Geyersberg (26 May 1768 – 23 July 1820), the daughter of Lt. Col. Baron Ludwig Heinrich Philipp Geyer von Geyersberg and his wife, Countess Maximiliana Christiane von Sponeck. Because his marriage to Luise was considered by the House of Baden as morganatic, Wilhelm, for a time, had no succession rights to the Grand Duchy.
The generations indicate descent from Charles Frederick, the first Grand Duke of a united Baden. Only princes notable enough for standalone articles are included. Later generations do not legally hold a title due to the abolition of the monarchy in 1918.
