2017 Welsh local elections

The 2016 Welsh local elections were held on 4 May 2017 to elect members of all 22 local authorities in Wales. This included the Isle of Anglesey, which was previously up for election in 2013 due to having its elections delayed for a year. Community council elections also took place on the same day. These local elections were held as part of the 2017 local elections in the United Kingdom. Apart from Anglesey, the last elections were held in 2012. Normally these elections take place every four years, but the 2017 elections were postponed for a year in order to avoid clashing with the 2016 Welsh Assembly election, which itself had been postponed by a year to avoid clashing with the 2015 general election.
