The Land of Israel (Hebrew: אֶרֶץ יִשְׂרָאֵל, Modern: Éretz Yisra'él, Tiberian: ʾEreṣ Yīsrāʾēl) is the traditional Jewish name for an area of the Southern Levant. Related biblical, religious, and historical English terms include the Land of Canaan, the Promised Land, the Holy Land, and Palestine. The definitions of the limits of this territory vary between passages in the Hebrew Bible, with specific mentions in Genesis 15, Exodus 23, Numbers 34 and Ezekiel 47. Nine times elsewhere in the Bible, the settled land is referred as "from Dan to Beersheba", and three times it is referred as "from the entrance of Hamath unto the brook of Egypt" (1 Kings 8:65, 1 Chronicles 13:5 and 2 Chronicles 7:8).

These biblical limits for the land differ from the borders of established historical Israelite and later Jewish kingdoms, including the United Kingdom of Israel, the two kingdoms of Israel (Samaria) and Judah, the Hasmonean kingdom, and the Herodian kingdom. At their heights, these realms ruled lands with similar but not identical boundaries.

Jewish religious belief defines the land as where Jewish religious law prevailed and excludes territory where it was not applied. It holds that the area is a God-given inheritance of the Jewish people based on the Torah, particularly the books of Genesis, Exodus, Numbers and Deuteronomy, as well as Joshua and the later Prophets (Exodus 6:4: "I also established my covenant with them to give them the land of Canaan, where they resided as foreigners"). According to the Book of Genesis, the land was first promised by God to Abram's descendants; the text is explicit that this is a covenant between God and Abram for his descendants (Gen 15:18–21 (NIV): "On that day the LORD made a covenant"). Abram's name was later changed to Abraham, with the promise refined to pass through his son Isaac and to the Israelites, descendants of Jacob, Abraham's grandson. This belief is not shared by most adherents of replacement theology (or supersessionism), who hold the view that the Old Testament prophecies were superseded by the coming of Jesus, a view often repudiated by Christian Zionists as a theological error. Evangelical Zionists variously claim that Israel has title to the land by divine right, or by a theological, historical and moral grounding of attachment to the land unique to Jews (Parkes, James). The idea that ancient religious texts can be warrant or divine right for a modern claim has often been challenged, and Israeli courts have rejected land claims based on religious motivations.

During the League of Nations mandate period (1920–1948) the term "Eretz Yisrael" or the "Land of Israel" was part of the official Hebrew name of Mandatory Palestine. Official Hebrew documents used the Hebrew transliteration of the word "Palestine" פלשתינה (Palestina) followed always by the two initial letters of "Eretz Yisrael", א״י Aleph-Yod.^{[page needed]}

The Land of Israel concept has been evoked by the founders of the State of Israel. It often surfaces in political debates on the status of the West Bank, referred to in official Israeli discourse as the Judea and Samaria Area.

The term "Land of Israel" is a direct translation of the Hebrew phrase ארץ ישראל‎ (Eretz Yisrael), which occasionally occurs in the Bible, and is first mentioned in the Tanakh in 1 Samuel 13:19, following the Exodus, when the Israelite tribes were already in the Land of Canaan. The words are used sparsely in the Bible: King David is ordered to gather 'strangers to the land of Israel' (hag-gêrîm 'ăšer, bə'ereṣ yiśrā'êl) for building purposes (1 Chronicles 22:2), and the same phrasing is used in reference to King Solomon's census of all of the 'strangers in the Land of Israel' (2 Chronicles 2:17). Ezekiel, although generally preferring the phrase 'soil of Israel' ('admat yiśrā'êl), employs eretz Israel twice, respectively at Ezekiel 40:2 and Ezekiel 47:18.

According to Martin Noth, the term is not an "authentic and original name for this land", but instead serves as "a somewhat flexible description of the area which the Israelite tribes had their settlements". According to Anita Shapira, the term "Eretz Yisrael" was a holy term, vague as far as the exact boundaries of the territories are concerned but clearly defining ownership. The sanctity of the land (kedushat ha-aretz) developed rich associations in rabbinical thought, where it assumes a highly symbolic and mythological status infused with promise, although always connected to a geographical location. Nur Masalha argues that the biblical boundaries are "entirely fictitious", and bore simply religious connotations in Diaspora Judaism, with the term only coming into ascendency with the rise of Zionism.

The Hebrew Bible provides three specific sets of borders for the "Promised Land", each with a different purpose. Neither of the terms "Promised Land" (Ha'Aretz HaMuvtahat) or "Land of Israel" are used in these passages: Genesis 15:13–21, Genesis 17:8 and Ezekiel 47:13–20 use the term "the land" (ha'aretz), as does Deuteronomy 1:8 in which it is promised explicitly to "Abraham, Isaac and Jacob... and to their descendants after them", whilst Numbers 34:1–15 describes the "Land of Canaan" (Eretz Kna'an) which is allocated to nine and half of the twelve Israelite tribes after the Exodus. The expression "Land of Israel" is first used in a later book, 1 Samuel 13:19. It is defined in detail in the exilic Book of Ezekiel as a land where both the twelve tribes and the "strangers in (their) midst", can claim inheritance. The name "Israel" first appears in the Hebrew Bible as the name given by God to the patriarch Jacob (Genesis 32:28). Deriving from the name "Israel", other designations that came to be associated with the Jewish people have included the "Children of Israel" or "Israelite".
