The 2014 E3 Harelbeke was the 57th running of the E3 Harelbeke single-day cycling race. It was held on 28 March 2014, over a distance of 212 kilometres (131.7 miles) and was the sixth race of the 2014 UCI World Tour season. The race was won by Peter Sagan in a four-man sprint finish.
As E3 Harelbeke was a UCI World Tour event, all 18 UCI ProTeams were invited automatically and obligated to send a squad. Seven other squads were given wildcard places, thus completing the 25-team peloton.
