2018 Taiwanese local elections

Local elections were held on 24 November 2018 in Taiwan, to elect county magistrates, county councilors, township mayors, township councilors and chiefs of village in 6 municipalities and 16 counties. Elected officials would serve a four-year term. Polling stations were open from 08:00 to 16:00 on the election day.
The elections resulted in a substantial defeat for the DPP. The DPP previously held 13 of 22 municipalities and counties, but won only 6 in this election due to widespread public distrust, a de facto vote of no confidence on President Tsai's Administration, both politically, economically, and socially, which were reflected in the series of referendum results. The KMT won back executive control of 7 municipalities and counties from the DPP, while Ko Wen-je won his re-election for Taipei mayor.
