Prince Tassilo Wilhelm Humbert Leopold Friedrich Karl of Prussia (April 6, 1893 – April 6, 1917) was a German prince and horse rider who competed in the 1912 Summer Olympics.
Prince Friedrich Karl von Preußen was born in Schloss Klein-Glienicke, Potsdam/Berlin. He was the son of Prince Friedrich Leopold of Prussia (1865-1931) and Princess Louise Sophie of Schleswig-Holstein-Sonderburg-Augustenburg (1866-1952) and a grandson of Prince Frederick Charles of Prussia.
He was part of the German team, which was able to win a bronze medal in the equestrian team jumping event. His horse during the Olympic competition was "Gibson Boy".
He fought in World War I between 1914 and 1917. He commanded FA(A)258, but flew patrols in a single seat fighter with Jasta Boelcke whenever possible. During one such patrol on March 21, 1917 he was forced to land with a bullet in his engine and a slight wound to his foot. He landed his Albatros aircraft in no-man's land, but while running towards his own lines he was severely wounded in the back by Australian troops. He was taken into Australian war captivity where he died from his injuries on April 6, 1917 at Saint-Étienne-du-Rouvray.
