World Mizrachi, commonly known as Mizrachi, is a prominent religious Zionist organization founded in 1902 in Vilnius (then part of the Russian Empire, now Lithuania) by Rabbi Yitzchak Yaacov Reines during a world conference of religious Zionists. The name 'Mizrachi' is a Hebrew acronym for 'Merkaz Ruhani,' meaning 'Spiritual Center,' emphasizing its role as a spiritual anchor within the Zionist movement. Rabbi Reines, who served as rabbi in Lida until his death, published the book 'Or Hadash al Tzion' (A New Light on Zion) that same year to counter anti-Zionist arguments from Orthodox rabbis, laying the ideological foundation for the organization. Mizrachi sought to integrate religious observance with Zionist goals, promoting the establishment of a Jewish state in line with Torah principles.

Headquartered in Jerusalem, Israel, World Mizrachi operates globally as a Torah-driven, community-focused educational entity committed to strengthening Jewish identity, destiny, and connection to Israel. It supports Orthodox Jewish life through initiatives like synagogues, schools, community programs, and aliyah (immigration to Israel) encouragement. The organization is closely associated with Bnei Akiva, its youth movement founded in 1929, which engages young people in religious Zionist activities worldwide. Under the leadership of Rabbi Doron Perez, Mizrachi provides resources such as the HaMizrachi Parsha Weekly publication and has organized over 85 solidarity missions to Israel since the onset of recent conflicts, involving thousands of participants. It receives financial support from the World Zionist Organization, enabling its extensive network of educational and settlement efforts.

As an international movement, World Mizrachi continues to function across continents, fostering religious education and Zionist settlement while distinguishing itself from unrelated terms like 'Mizrahim' (Jews of Eastern descent). Its activities include innovative programs like Sulamot, which address social issues, and it remains a key player in promoting Orthodox perspectives within global Judaism and Zionism.
