Moshe Unna (Hebrew: משה אונא, 22 November 1902 – 21 February 1989) was an Israeli politician who served as a member of the Knesset for the United Religious Front, Hapoel HaMizrachi and the National Religious Party between 1949 and 1969.

Born in Mannheim in Germany, Unna attended an agricultural school and a rabbinical seminary in Berlin, earning a diploma in agronomy.

In 1937, he helped establish Tirat Zvi, a religious Kibbutz in the Beit She'an Valley.

Two years later he became a member of Hapoel HaMizrachi's executive committee, serving as treasurer from 1942 until 1949.

In 1955 Hapoel HaMizrachi and Mizrachi allied to form the National Religious Party (which became a formal merger the following year), and Unna was re-elected on its list.
