The Chief Rabbinate of Israel (Hebrew: הָרַבָּנוּת הָרָאשִׁית לְיִשְׂרָאֵל, Ha-Rabbanut Ha-Rashit Li-Yisra'el) is recognized by law as the supreme rabbinic authority for Judaism in Israel. The Chief Rabbinate Council assists the two Chief Rabbis, who alternate in its presidency. It has legal and administrative authority to organize religious arrangements for Israel's Jews. It also responds to halakhic questions submitted by Jewish public bodies in the Diaspora. The Council sets, guides, and supervises agencies within its authority.

The Chief Rabbinate of Israel consists of two Chief Rabbis: an Ashkenazi rabbi, and a Sephardi rabbi; the latter also is known as the Rishon leZion. The Chief Rabbis are elected for 10-year terms. The present Sephardi Chief Rabbi is Yitzhak Yosef, and the Ashkenazi Chief Rabbi is David Lau, both of whom began their terms in 2013.

The Rabbinate has jurisdiction over many aspects of Jewish life in Israel. Its jurisdiction includes personal status issues, such as Jewish marriages and Jewish divorce, as well as Jewish burials, conversion to Judaism, kosher laws and kosher certification, Jewish immigrants to Israel (olim), supervision of Jewish holy sites, working with various ritual baths (mikvaot) and yeshivas, and overseeing Rabbinical courts in Israel.

The Rabbinical courts are part of Israel's judicial system, and are managed by the Ministry of Religious Services. The courts have exclusive jurisdiction over marriage and divorce of Jews, and have parallel competence with district courts in matters of personal status, alimony, child support, custody, and inheritance. Religious court verdicts are implemented and enforced — as for the civil court system — by the police, bailiff's office, and other agencies.

The Chief Rabbinate headquarters are located at Beit Yahav building, 80 Yirmiyahu Street, Jerusalem. The former seat of the institution, the Heichal Shlomo building, has been serving since 1992 mainly as a museum.
