Otniel (Hebrew: עָתְנִיאֵל) is an Orthodox Israeli settlement in the West Bank. Located in the southern Judaean Mountains, south of Hebron, it falls under the jurisdiction of Har Hevron Regional Council. In 2023, it had a population of 1,016.

Otniel is named after the first biblical judge of Israel, Othniel Ben Kenaz; the settlement is located between the Palestinian cities of Yatta and Dahariya, adjacent to Highway 60, which connects Jerusalem and Be'er Sheva.

Othniel serves as a regional center in the Hebron Hills and hosts numerous educational institutions: a Hesder Yeshiva, a high school yeshiva, a middle school, and a regional elementary school for the children of the settlement and the surrounding area. The nearby Jewish settlements to Othniel are Beit Hagai to the north and Shim'a and Mitzpe Eshtemoa to the south.

The international community considers Israeli settlements in the West Bank illegal under international law, but the Israeli government disputes this.

The settlement was established in 1983 south of Beit Hagai and north of Shim'a and the Palestinian villages of as-Samu, Yatta and ad-Dhahiriya. The settlement is named after the Biblical judge Otniel Ben Knaz.

The international community considers all Israeli settlements in the West Bank to violate the Fourth Geneva Convention's prohibition on the transfer of an occupying power's civilian population into occupied territory. Israel disputes that the Fourth Geneva Convention applies to the Palestinian territories as they had not been legally held by a sovereign prior to Israel taking control of them. This view has been rejected by the International Court of Justice and the International Committee of the Red Cross.

Otniel is served by Highway 60 (Israel–Palestine), a major north-south highway in the West Bank.

Entry to Beersheba via Highway 60 is controlled by the Meitar Israeli checkpoint, where green (Palestinian Authority) registered vehicles are barred from access.
