The Alsace single territorial collectivity referendum (French: référendum sur la Collectivité territoriale d'Alsace) was a referendum held on Sunday, 7 April 2013 in Alsace, France, which aimed at the creation of the single territorial collectivity of Alsace through the merging of the regional council of Alsace and the departmental councils of Bas-Rhin and Haut-Rhin. Even though there was a 57.65% majority of "Yes" votes, the project was not approved: indeed, the "Yes" side needed to win in both departments (and at least 50% overall) with at least a 25% share of the vote from eligible voters (188,027 votes in Bas-Rhin and 130,439 votes in Haut-Rhin). The project was rejected by 55.74% of the voters in Haut-Rhin, whereas the "Yes" side won only a 22.90% share from eligible voters in Bas-Rhi
