Zalman Shazar (Hebrew: זלמן שזר; November 24, 1889 – October 5, 1974) was an Israeli politician, author and poet.

Shazar was born Shneur Zalman Rubashov to a Hasidic family of the Chabad-Lubavitch denomination in Mir, near Minsk, in the Russian Empire (today in Grodno Region, Belarus).

He remained involved with Chabad for the rest of his life, assisting Rabbi Yosef Yitzchok Schneersohn, the sixth Lubavitcher Rebbe in founding the village of Kfar Chabad, and at his behest, allowed the religious community in Israel to set up their own educational system.

In 1924, after his release, he immigrated to the British Mandate of Palestine, settling in Tel Aviv, and became a member of the secretariat of the Histadrut.

In 1947, he was a member of the Jewish Agency's delegation to the negotiations for the UN partition plan for Palestine and played a key role in drafting Israel's Declaration of Independence.
