Ir Ovot (Hebrew: עִיר אֹבֹת ,עיר אובות, Ir Obot; lit. City of Oboth), was an agricultural cooperative (kibbutz) in Israel 1967–1980s, located in the northeastern Negev's Arava region, and still refers to a small, group of homes near New Ein Hatzeva.
It is the site of an extensive archaeological complex known as Tamar Fortress or Hatzevah Fortress (Hebrew: מצודת חצבה) which dates to the 10th century BCE (United Monarchy/First Temple period).
Ir Ovot is located south of the Dead Sea and southeast of Dimona in the Arabah valley, an arid plain located below the Negev plateau and south of the Jordan Rift Valley within the larger Great Rift Valley. The settlement abuts the Ein Hatzeva bloc of agricultural villages on the opposite side of Highway 90 near the Jordanian border, and is within the boundaries of the Arava Regional Council.
Originally the site of the Ein Husub police station during the British Mandate of Palestine, the location was captured by the Israel Defense Forces in 1948. The village of Ir Ovot was founded in 1967, in an area deserted apart from a small military base and roadside cafe on the way to Eilat. It was founded by a group of American Jews led by former law student and court clerk Rabbi Simcha Pearlmutter, a Jew from Miami, Florida.
