Israeli settlements, also called Israeli colonies, are the civilian communities built by Israel throughout the Israeli-occupied territories. They are populated by Israeli citizens, almost exclusively of Jewish identity or ethnicity, and have been constructed on lands that Israel has militarily occupied since the Six-Day War in 1967. The international community considers Israeli settlements to be illegal under international law, but Israel disputes this. In 2024, the International Court of Justice (ICJ) found in an advisory opinion that Israel's occupation was illegal and ruled that Israel had "an obligation to cease immediately all new settlement activities and to evacuate all settlers" from the occupied territories. The expansion of settlements often involves the confiscation of Palestinian land and resources, leading to displacement of Palestinian communities and creating a source of tension and conflict. Settlements are often protected by the Israeli military and are frequently flashpoints for violence against Palestinians. Furthermore, the presence of settlements and Jewish-only bypass roads creates a fragmented Palestinian territory, seriously hindering economic development and freedom of movement for Palestinians.
As of April 2025, Israeli settlements exist in the West Bank (including East Jerusalem), which is claimed by the Palestine Liberation Organization (PLO) as the sovereign territory of the State of Palestine, and in the Golan Heights, which is internationally recognized as a part of the sovereign territory of Syria. Through the Jerusalem Law and the Golan Heights Law, Israel effectively annexed both territories, though the international community has rejected any change to their status as occupied territory. Although Israel's West Bank settlements have been built on territory administered under military rule rather than civil law, Israeli civil law is "pipelined" into the settlements, such that Israeli citizens living there are treated similarly to those living in Israel. Many consider it to be a major obstacle to the Israeli–Palestinian peace process. In Legal Consequences of the Construction of a Wall in the Occupied Palestinian Territory (2004), the ICJ found that Israel's settlements and the then-nascent Israeli West Bank barrier were both in violation of international law; part of the latter has been constructed within the West Bank, as opposed to being entirely on Israel's side of the Green Line.
