An election to Derbyshire County Council took place on 4 May 2017 as part of the 2017 United Kingdom local elections. 64 councillors were elected from 61 electoral divisions which returned either one or two county councillors each by first-past-the-post voting for a four-year term of office. No elections were held in the City of Derby, which is a unitary authority outside the area covered by the County Council. The Conservative Party won back control of the council, taking thirty-seven of the authority's sixty-four seats.
