The Euler is an edge jump in figure skating. The Euler jump was known as the half loop jump in International Skating Union (ISU) regulations prior to the 2018/19 season when the name was changed.{{cite web |last1=Cornetta |first1=Katherine |date=1 October 2018 |title=Breaking Down an Euler |url=https://usfigureskatingfanzone.com/news/2018/10/1/figure-skating-breaking-down-an-euler.aspx |access-date=3 July 2024 |website= |publisher=U.S. Figure Skating}} Its invention has been attributed to both to Carl and Gustav Euler, two Austrian brothers who won the men's pairs competition at the 1900 European Championships,{{Cite journal |last=Kluge |first=Volker |date=2018 |title=Gillis Grafström – the Artist among the Figure Skaters |url=https://isoh.org/wp-content/uploads/2019/02/362.pdf |journal=Journal of Olympic History |volume=26 |issue=2 |pages=24–33}} as well as to Swedish figure skater Per Thorén, who won a bronze medal at the 1908 Olympics in London. It is thus also called the Thorén jump in Europe.{{cite book |last1=Hines |first1=James R. |url= |title=Historical Dictionary of Figure Skating |date=2011 |publisher=Scarecrow Press |isbn=978-0-8108-6859-5 |location=Lanham, Maryland |page=222}} It is also a jump used in artistic roller skating.{{cite news |last1=Walker |first1=Elvin |date=19 September 2018 |title=New Season New Rules |url=https://www.ifsmagazine.com/new-season-new-rules/ |url-status=dead |archive-url=https://web.archive.org/web/20240302104237/https://www.ifsmagazine.com/new-season-new-rules/ |archive-date=2 March 2024 |access-date=3 July 2024 |work=International Figure Skating}}

The Euler is performed when a skater takes off from the back outside edge of one skate and lands on the back inside edge on the opposite foot. It is most commonly done prior to the third jump during a three-jump combination and serves as a way to put a skater on the correct edge in order to attempt a Salchow jump or a flip jump. It is only recognized as a listed jump when performed with a single rotation.

According to U.S. Figure Skating, two benefits of the name change are that it simplifies the notation system for judges and makes it easier for skaters to attempt three-jump combinations, even if single loop jumps are already a planned part of their programs or if they accidentally pop out of a previous loop jump. When used in combination with two listed jumps, the Euler is counted as a listed jump with a base point value of 0.50 points.{{cite web |date=23 May 2018 |title=Communication No. 2168: Single & Pair Skating |url=https://www.isu.org/figure-skating/rules/fsk-communications/17142-isu-communication-2168/file |url-status=dead |archive-url=https://web.archive.org/web/20220321223247/https://www.isu.org/figure-skating/rules/fsk-communications/17142-isu-communication-2168/file |archive-date=21 March 2022 |access-date=3 July 2024 |publisher=International Skating Union |page=2 |location=Lausanne, Switzerland}}{{cite web |date=2022 |title=Special Regulations & Technical Rules Single & Pair Skating and Ice Dance 2022 |url=https://www.isu.org/figure-skating/rules/fsk-regulations-rules/file |access-date=3 July 2024 |publisher=International Skating Union |page=103}}
