The 2017 Rhondda Cynon Taf Council election took place on Thursday 4 May 2017 to elect members of Rhondda Cynon Taf County Borough Council in Wales. This was the same day as other 2017 United Kingdom local elections. The previous full council election took place on 3 May 2012.
Seventy four council seats across fifty two electoral wards were up for election. Labour remained in control of the council, though lost thirteen seats overall, while Plaid Cymru doubled their numbers to eighteen. Labour council leader Andrew Morgan described the result as "a reasonably good outcome considering the circumstances we have been facing", while Plaid Cymru group leader Pauline Jarman said she was "slightly disappointed". A "shock" result was the election of a councillor from new party, The Cynon Valley Party, to the Penrhiwceiber ward.
