The 2007 World Allround Speed Skating Championships were held in the indoor arena Thialf in Heerenveen, Netherlands on 9–11 February 2007. The Championships were three-day allround events, with the skaters completing four distances before the final championship standings are determined based on the samalog system. The organising body, the Koninklijke Nederlandsche Schaatsenrijders Bond (KNSB), celebrated its 125-year anniversary with full stands on all three days.
Athletes from the host country, the Netherlands, won both the men's and the women's event; Sven Kramer set a world record on the men's 10,000 metres on his way to the European and World Allround double, while Ireen Wüst won by nearly two points after being narrowly beaten by Martina Sáblíková at the European Championships. For the first time since 1979, the male and female World Champion came from the same country. Defending champion Shani Davis finished sixth after losing time on the two longest distances, while former sprint World Champion Erben Wennemars debuted at the World Allround Championships with a fifth place. Last year's female champion, Cindy Klassen, finished third, a quarter of a point behind Anni Friesinger, who did not compete in 2006.
