Halhul (Arabic: حلحول, transliteration: Ḥalḥūl) is a Palestinian city located in the southern West Bank, 5 kilometres (3.1 mi) north of Hebron in the Hebron Governorate of the State of Palestine. The town, bordered by Sa'ir and Ash-Shuyukh to the east, Beit Ummar and Al-Arroub refugee camp to the north, and Kharas and Nuba westwards, is located 916 m above sea level, and is the highest inhabited place in Palestine. According to the Palestinian Central Bureau of Statistics, the city had a population of 22,108 mostly Muslim inhabitants in 2007.

According to Jewish, Christian and Muslim medieval traditions, the graves of the biblical prophets Gad and Nathan are located in Halhul. The burial site of prophet Nathan is described as a cave covered in a green color and caged off from the public. Another Muslim tradition places Jonah's grave in the town. The burial sites, formerly designated in the list of Holy Places under Israeli rule, are now under the Palestinian Authority.

The Israeli settlement of Karmei Tzur lies on the outskirts of Halhul. Halhul is surrounded by ancient burial caves.
