Suining County (simplified Chinese: 睢宁县; traditional Chinese: 睢寧縣; pinyin: Suīníng Xiàn; Wade–Giles: Sui-ning) is under the administration of Xuzhou, Jiangsu province, China; it is the southernmost county-level division of Xuzhou and borders the prefecture-level cities of Suqian to the east and Suzhou of Anhui to the south and west.
Suining basically was a part of former Suiling (睢陵) county by the Han. The seat of the Suiling was relocated to present-day Suining during the Three Kingdoms, and Suiling was merged into Suqian later. In 1218, it became a separate county seated at the old walled city of Suqian, and named "Suining" (literally: Bring peace to the Sui basin). The county was defunct in early Yuan, but restored in 1275. It was under Pizhou of Huai'an until Pizhou became a part of Xuzhou in 1733.
