Israeli Jews or Jewish Israelis (Hebrew: יהודים ישראלים Yêhūdīm Yīśrāʾēlīm) comprise Israel's largest ethnic and religious community. The core of their demographic consists of those with a Jewish identity and their descendants, including ethnic Jews and religious Jews alike. About 46% of the global Jewish population resides in Israel; yerida is uncommon and is offset exponentially by aliyah, but those who do emigrate from the country typically move to the Western world. As such, the Israeli diaspora is closely tied to the broader Jewish diaspora.

Israel is widely described as a melting pot for the various Jewish ethnic divisions, primarily consisting of Ashkenazi Jews, Sephardic Jews, and Mizrahi Jews, as well as many smaller Jewish communities, such as the Beta Israel, the Cochin Jews, the Bene Israel, and the Karaite Jews, among others. Over 25% of Jewish children and 35% of Jewish newborns in Israel are of mixed Ashkenazi and Sephardic or Mizrahi descent, and these figures have been increasing by approximately 0.5% annually: over 50% of Israel's entire Jewish population identifies as having Ashkenazi, Sephardic, and Mizrahi admixture. The integration of Judaism in Israeli Jewish life is split along four categories: the secularists (33%), the traditionalists (24%), the Orthodox (9%), and the Ultra-Orthodox (7%). In addition to religious influences, both Jewish history and Jewish culture serve as important aspects defining Israel's Jewish society, thereby contributing significantly to Israel's identity as the world's only Jewish-majority country.

In 2018, Israel's Knesset narrowly voted in favour of Basic Law: Israel as the Nation-State of the Jewish People. As the Israeli government considers a person's Jewish status to be a matter of nationality and citizenship, the definition of Jewishness in the Israeli Law of Return includes patrilineal Jewish descent; this does not align with the stipulations of Judaism's halakha, which defines Jewishness through matrilineality. As of 1970^[update], all Jews by blood and their spouses automatically qualify for the right to immigrate to the country and acquire Israeli citizenship.

According to the Israel Central Bureau of Statistics, the Israeli Jewish population stood at 7,208,000 in 2023, comprising about 73% of the country's total population. Including non-Jewish relatives (e.g., spouses) raises this figure to 7,762,000, about 79% of the country's population. A 2008 Israel Democracy Institute study found that a plurality of Israeli Jews (47%) identify as Jews first and as Israelis second, and that 39% consider themselves Israelis first and foremost.

Upon the Israeli Declaration of Independence in 1948, the Palestinian Jews of the Yishuv in the British Mandate for Palestine became known as Israeli Jews due to their adoption of a new national identity. The former term has since fallen out of common use.

Jews have long considered the Land of Israel to be their homeland, even while living in the diaspora. According to the Hebrew Bible the connection to the Land of Israel began in the covenant of the pieces when the region, which is called the land of Canaan, was promised to Abraham by God. Abraham settled in the region, where his son Isaac and grandson Jacob grew up with their families. Later on, Jacob and his sons went to Egypt. Decades later their descendants were led out of Egypt by Moses and Aaron, given the Tablets of Stone, returned to the land of Canaan and conquered it under the leadership of Joshua. After the period of the judges, in which the Israelites did not have an organized leadership, the Kingdom of Israel was established, which constructed the First Temple. This kingdom was soon split into two—the Kingdom of Judah and the Kingdom of Israel. After the destruction of these kingdoms and the destruction of the First Temple, the Israelites were exiled to Babylon. After about 70 years parts of the Israelites were permitted to return to the region and soon thereafter they built the Second Temple. Later they established the Hasmonean Kingdom. The region was conquered by the Roman Empire in 63 BCE. During the first couple of centuries in the common era during a series of rebellions against the Roman Empire the Second Temple was destroyed and there was a general expulsion of Jews from their homeland.

The area was later conquered by migrant Arabs who invaded the Byzantine Empire and established a Muslim Caliphate in the 7th century during the rise of Islam. Throughout the centuries the size of the Jewish population in the land fluctuated. Before the birth of modern Zionism in the 1880s, by the early 19th century, more than 10,000 Jews were still living in the area that is today modern Israel.

Following centuries of Jewish diaspora, the 19th century saw the rise of Zionism, a Jewish nationalist movement that had a desire to see the self-determination of the Jewish people through the creation of a homeland for the Jews in Palestine. Significant numbers of Jews have immigrated to Palestine since the 1880s. Zionism remained a minority movement until the rise of Nazism in 1933 and the subsequently attempted extermination of the Jewish people in Nazi-occupied areas of Europe in the Holocaust. In the late 19th century large numbers of Jews began moving to the Ottoman and later British-controlled region. In 1917, the British endorsed a National Home for Jews in Mandate Palestine by issuing the Balfour Declaration. The Jewish population in the region increased from 11% of the population in 1922 to 30% by 1940.
