This list of speed skating records is an overview of the records currently held in various speed skating events, as ratified by the International Skating Union.
World records
Men
* Seven skaters have a recorded a 3000m time below this world record on this irregularly competed distance, including Denis Yuskov, who recorded a 3000m time of 3:34.37 during a training race held on 2 November 2013. However, the race had a so-called 'quartet-start' (four riders on the track at the same time as opposed to the usual two), making it ineligible to be counted as a world record under Article 221(2)(i) of the rules of the International Skating Union. Several skaters have recorded 3000m split times below 3:37.28 during a 5000m race, including Sven Kramer as early as November 17, 2007, but split times do not count as world records either. ** The average speed for the team pursuit race was calculated using a distance of 3098,88 meters for the men's race. The skaters only utilize the inner lane and the lap distance is accordingly less than the 400 meters of a regular lap skated with one inner curve and one outer curve. For comparison, the fastest known 400m lap was skated by Pavel Kulizhnikov on 9 March 2019 in Salt Lake City during his 500-meter world record race, with a lap time of 23.94 seconds and an average speed of . *** unofficial world best (not recognized as a world record by ISU)
Women
** The average speed for the team pursuit race was calculated using a distance of 2324,16 meters for the women's race. The skaters only utilize the inner lane and the lap distance is accordingly less than the 400 meters of a regular lap skated with one inner curve and one outer curve. For comparison, the fastest known 400m lap was skated by Zhang Hong during a 500m race in Salt Lake City on 20 November 2015, with a lap time of 25.93 seconds and an average speed of . *** unofficial world best (not recognized as a world record by ISU)
Sea-level world bests
Salt Lake City and Calgary, where most of the current world records were set (see above), are at comparatively high altitudes (greater than 1 km above sea level). Performance is better at these high altitudes because the lower oxygen levels are compensated by the reduced air resistance. Skating statisticians therefore record separate lists of "sea-level world bests" for speed skating records that are set at (or close to) sea level, from which results in Salt Lake City and Calgary are excluded.
