The Schleswig plebiscites were two plebiscites, organized according to section XII, articles 100 to 115 of the Treaty of Versailles of 28 June 1919, in order to determine the future border between Denmark and Germany through the former Duchy of Schleswig. The process was monitored by a commission with representatives from France, the United Kingdom, Norway and Sweden.

The plebiscites were held on 10 February and 14 March 1920, and the result was that the larger northern portion (Zone I) voted to join Denmark, which occurred 15 June 1920, while the smaller southern portion (Zone II) voted to remain part of Germany.
