The 2014 St. Charles County Executive election took place on November 4, 2014. Incumbent Republican County Executive Steve Ehlmann ran for re-election to a third term. He initially faced a challenge in the Republican primary from State Representative Doug Funderburk, but Funderburk withdrew from the race, citing family concerns. Ehlmann won the Republican primary and faced Rodney Zerr, the county's former Director of Emergency Management, in the general election. Ehlmann defeated Zerr by a wide margin, winning his third term with 68 percent of the vote.
