Yedisan (also Jedisan or Edisan; Ukrainian: Єдисан, romanized: Yedysan, Romanian: Edisan, Turkish: Yedisan, Russian: Едисан, romanized: Yedisan, Dobrujan Tatar: Cedĭsan) was a conditional name for Özi [Paşa] Sancağı (Ochakiv Sanjak) of Silistra Eyalet, a territory located in today's Southern Ukraine between the Dniester and the Southern Bug (Boh), which was placed by the Ottomans under the control of the Nogai Horde in the 17th and 18th centuries and was named after one of the Nogai Hordes. In the Russian Empire, it was referred to as Ochakov Oblast, while the Ottoman Turks called it simply Özü after the city of Ochakiv which served as its administrative center. Another name used was Western Nogai.

Geographically, it was the western part of the so-called Wild Fields that sprawled to the north of the Black Sea between the Dniester and Dnieper rivers. It lies east of Budjak and Bessarabia, south of Podolia and Zaporizhzhia, and west of Taurida. Since the mid-20th century, the territory has been divided between southwestern Ukraine and southeastern Moldova (southern Transnistria).
