The 2013 E3 Harelbeke was the 56th running of the E3 Harelbeke single-day cycling race. It was held on 22 March 2013, over a distance of 211 kilometres (131.1 miles) and was the sixth race of the 2013 UCI World Tour season.
As E3 Harelbeke was a UCI World Tour event, all UCI ProTeams were invited automatically and obligated to send a squad. Originally, eighteen ProTeams were invited to the race, with six other squads given wildcard places, and as such, would have formed the event's 24-team peloton. Team Katusha subsequently regained their ProTour status after an appeal to the Court of Arbitration for Sport.[3][4] With Team Katusha not originally invited to the race, race organisers announced their inclusion to the race, bringing the total number of teams competing to twenty-five. Each of the 25 teams entered eight riders to the race, making up a starting peloton of 200 riders.
