Leon Štukelj

Leon Štukelj (; 12 November 1898 – 8 November 1999) was a Slovene professional gymnast. He was an Olympic gold medalist and athlete who represented Yugoslavia at the Olympics.

He is a noted figure in Slovenian sporting history. Štukelj is one of the first Slovene athletes to have risen to the very top of his sport, where he remained right from the World Championships in Ljubljana in 1922 all the way to the 1936 Olympic Games in Berlin, at which point he finished his competitive gymnastics career.

Štukelj competed at seven major international competitions and won a total of twenty medals: eight gold, six silver, and six bronze. At the Olympic Games alone he won six medals: two gold medals (counted for Yugoslavia) in Paris in 1924, one gold medal and two bronze in Amsterdam in 1928 and a silver medal in Berlin in 1936.
