Yambol (Bulgarian: област Ямбол, oblast Yambol, former name Yambol okrug) is a province in southeastern Bulgaria, neighbouring Turkey to the south. It is named after its main city Yambol, while other towns include Straldzha, Bolyarovo and Elhovo. The province embraces a territory of 3,355.5 km (1,295.6 sq mi) that is divided into five municipalities with a total population, as of December 2009, of 138,429.

The Vilayet of Adrianople or Vilayet of Edirne (Ottoman Turkish: ولايت ادرنه; Vilâyet-i Edirne) was a first-level administrative division (vilayet) of the Ottoman Empire.

Prior to 1878, the vilayet had an area of 26,160 square miles (67,800 km) and extended all the way to the Balkan Mountains. However, by virtue of the Treaty of Berlin (1878), the Sanjak of İslimye, most of the Sanjak of Filibe and a small part of the Sanjak of Edirne (the Kızılağaç kaza and Monastır nahiya) were carved out of it to create the autonomous province of Eastern Rumelia, with a total area of 32,978 km. The province unified peacefully with the Principality of Bulgaria in 1885.
