Sven Kramer (Dutch pronunciation: [sfɛŋ ˈkraːmər]; born 23 April 1986) is a retired Dutch long track speed skater who has won an all-time record nine World Allround Championships as well as a record ten European Allround Championships.

From November 2007 to March 2009, he was ranked first in the Adelskalender,[1] but despite his dominance as an all-round skater he has since been overtaken on that list by Shani Davis and, more recently, by his teammate Patrick Roest and Jordan Stolz.

On 27 March 2020, it was announced that Kramer extended his contract with the Jumbo-Visma speed skating team until the 2022 Winter Olympics.

[4] Since 2007 he has been in a long-term relationship with Dutch field hockey player Naomi van As, and they welcomed a daughter in October 2018.

On 3 March 2010, Kramer was awarded as Knight of the Order of the Netherlands Lion for his services to sport, i.e., winning the Men's 5000 m speed skating competition at the 2010 Winter Olympics in Vancouver.

The Dutch team was the favourite and was leading Italy by nearly a full second in their semi-final, but Kramer stepped on a block and fell, taking Carl Verheijen with him.

During the 2006 European Allround Championships in Hamar, Kramer reached fourth place after a tournament full of incidents.

By skating a new personal best in the 1500 m, Kramer overtook fellow Dutchman Jochem Uytdehaage and Enrico Fabris on the Adelskalender.

At the World Championships of 2007 in Salt Lake City, Kramer participated in the 5000, 10,000 meters, and the team pursuit.

In Kolomna, Russia, Kramer won the European Allround Championship for the second time.

On 10 February, Kramer became World Allround Champion in Berlin, Germany, for the second time.

In the 1500 meter event, Kramer skated a good race and placed second, ahead of Olympic Champion Enrico Fabris and Shani Davis.

At the world single distance championships in Vancouver, Kramer won gold in the 5000, 10,000 meters, and the team pursuit.

[12] He won the final 10,000 meter race from the Italian Enrico Fabris, who ended second in the overall rankings.

[14][15] He finished ahead of South Korean Lee Seung-hoon and Russian Ivan Skobrev, leaving four Olympic champions, Shani Davis, Enrico Fabris, Chad Hedrick and Bob de Jong, empty-handed.

"[16] In the 10,000 meter event, Kramer finished first, with a time of 12:54.50, only to be disqualified for incorrectly changing lanes during one of the later laps.

[17] The lane change mistake was caused by incorrect directions shouted to Kramer by his coach, Gerard Kemkers, near the end of the race.

[20] At the World allround championships in Heerenveen on 19–21 March 2010, Kramer won an unprecedented fourth consecutive title.

Kramer also won the World Allround Championships in Hamar in February for a record sixth time.

In preparation for the Winter Olympics, Kramer chose not to compete in the European allround championships.
