The Austro-Hungarian concession of Tianjin was a territory (concession) in the Chinese city of Tientsin occupied by Austria-Hungary between 1902 and 1920. It had been obtained by Austria-Hungary after the signing of the Boxer Protocol at the conclusion of the conflict between China and the Alliance of Eight Nations, which had sent an international expeditionary force to quell the Boxer Rebellion of 1901. Although the Austro-Hungarian occupation corps had been present from the previous year, the concession formally began on 27 December 1902. It is the shortest lived concession, having existed for only 14 years.
