Wilhelm Bogner (7 February 1909 – 27 July 1977), better known as Willy Bogner Sr., was a German Nordic skier who competed in the 1930s. He won a pair of medals at the FIS Nordic World Ski Championships with a silver in the 4 x 10 km event in 1934 and a bronze in the nordic combined in 1935. Bogner Sr. also finished 6th in the 4 x 10 km event and 12th in the Nordic combined at the 1936 Winter Olympics in Garmisch-Partenkirchen, where he also took the Olympic Oath.
During his career, Bogner Sr. was an eleven-time German and five-time nordic skiing champion. This allowed him to establish his clothing line in 1932, including outfitting the German national ski team at the 1936 Winter Olympics.
