Elections to Essex County Council took place on 4 May 2017 as part of the 2017 local elections. All 75 councillors were elected from 70 electoral divisions, which each returned either one or two councillors by first-past-the-post voting for a four-year term of office. The electoral divisions were the same as those used at the previous elections in 2009 and 2013. No elections were held in Thurrock or Southend-on-Sea, which are unitary authorities outside the area covered by the County Council.
