Popovo Polje (Bosnian: Popovo polje, Serbian Cyrillic: Попово поље, pronounced [pɔ̌pɔʋɔ pɔ̂ʎɛ], meaning priest's field) is a polje (karstic plain) in Bosnia and Herzegovina, located in a southernmost region of the country, near the Adriatic coast. Its size is 5.9 square kilometres (2.3 sq mi).
Popovo polje is one of the largest polje (karstic plains) in Bosnia and Herzegovina and the world, famous for its karstic phenomenons and features, and particularly the Trebišnjica river, which flows through the polje as the largest sinking river (also losing stream, or influent stream) in the world, as well as the Vjetrenica cave system, located to the west/south-western parts of the valley.
The Nikolić noble family and Sanković noble family held Popovo polje in the late Middle Ages. The Vojnović noble family hailed from Popovo polje. The Zavala Monastery was first mentioned in the 16th century. At the end of Ottoman rule in Herzegovina, the Muslibegović family had properties in Popovo polje.
Located in Popovo Polje in Ravno municipality, village Zavala with its old architecture and stone masonry, together with Vjetrenica cave, constitute the natural and architectural ensemble which is in the process of being protected as National Monument of Bosnia and Herzegovina, and it is already placed on UNESCO Tentative List.
