The 2013 Trinidadian local elections were held on 21 October 2013 to elect representatives in all 14 municipal corporation electoral areas in Trinidad. 136 seats were contested. These were the first elections held after the Municipal Corporations Amendment Act of 2013, which also provided for four aldermen in each corporation to be allocated by proportional representation. The People's National Movement was victorious in the election, winning the plurality of the vote and the majority of Municipal Corporations.
The Elections and Boundaries Commission recorded the highest voter turnout in history for a local government election. Eight municipal corporations were won by the opposition People's National Movement, five municipal corporations were won by the ruling People's Partnership, and the Chaguanas Municipal Corporation was divided 3-3-2 between PNM, UNC and ILP respectively. An ILP councilor later crossed the floor, giving the UNC control of the Chaguanas Borough Corporation.
