The 2017 Hampshire County Council election took place on 4 May 2017 as part of the 2017 local elections in the United Kingdom. All councillors were elected from electoral divisions by first-past-the-post voting for a four-year term of office. The electoral divisions were somewhat changed from the previous election, with some being split, merged or with boundary changes. No elections were held in Portsmouth and Southampton, which are unitary authorities and hold their elections in other years. Similarly the districts within Hampshire did also not hold elections this year.
The incumbent Conservatives (majority since 1997) increased their majority from 45 to 56, over a two thirds majority, whilst the Liberal Democrats, the second largest party, won two new seats, increasing their seats to 19.The Liberal Democrats performed best around Winchester, and Eastleigh, whilst the Conservatives performed well across rural areas. Labour and UKIP meanwhile both lost seats, with Labour losing two of their four seats in Basingstoke, whilst UKIP lost all representation across the County. Community Campaign (Hart) managed to retain their only seat, Church Crookham & Ewshot, while also standing in a second county seat for the first time in Fleet Town, where they came second place after the Conservatives, who won with a majority of 508. The Green Party also increased their vote share, but failed to gain representation. The sole Independent incumbent, in Lymington, lost their seat.
The Local Government Boundary Commission for England undertook a review of boundaries during the previous council's term. An Order to enact the boundary changes was made in October 2016 and took effect at this election.
