The sixth election to the Powys County Council since local government reorganization in Wales in 1995 was held on 4 May 2017, along with other local government elections. It was preceded by the 2012 election and was followed by the 2022 election.
Sixteen seats were uncontested and, in another seat, Yscir, no one initially stood at all for the seat (the only ward in Wales where this happened). Nine Independent seats, out of the thirty won, were due to only one candidate standing for election. Five of the seven Labour seats and one each of the Conservative and Liberal Democrat seats were also uncontested.
The sitting member had previously stood as a Conservative. His change is shown from when he stood as a Conservative in 2012.
No nominations received.
The postponed poll took place on 22 June 2017 and was won by the Conservative Iain McIntosh.
