2009–10 ISU Speed Skating World Cup

The 2009–10 ISU Speed Skating World Cup, officially the Essent ISU World Cup Speed Skating 2009–2010, was a series of international speed skating competitions which ran the entire season. The season started on 6 November 2009 in Berlin, Germany, and ended on 14 March 2010 in Heerenveen, Netherlands. Compared to previous seasons, fewer competition weekends were held; the season was restricted due to the 2010 Winter Olympics, which were arranged in Vancouver, Canada, during February 2010. In total, seven competition weekends were held at six different locations, ten cups were contested (five for men, and five for women), and 70 races took place.

The World Cup is organized by the International Skating Union (ISU).
