The 2008 Conwy Council election took place on 1 May 2008 to elect members of Conwy County Borough Council in Wales. It was on the same day as other 2008 United Kingdom local elections. The previous elections took place on 10 June 2004 and the following election took place on 3 May 2012.
Fifty nine county councillors were elected from the county's thirty eight electoral wards. The biggest gains were by the Conservative Party with eight additional seats, while the Labour Party and Independent group lost out. There were several very close results, with the Conservatives winning in Capelulo by 26 votes, the sitting veteran Labour councillor in Llandudno's Tudno losing by 27 votes and the Independent councillor in Llansannan winning by only four votes. Similarly to the previous Conwy elections in 1995, 1999 and 2004, no party or group ended in overal majority control.
