Moshe Kelmer (Hebrew: משה קלמר; 1 November 1901 – 11 September 1970) was an Israeli politician who served as a member of the Knesset in three spells between 1949 and 1963.

Born in Żychlin in the Russian Empire (today in Poland), Kelmer joined Young Mizrachi during his youth.

He later helped establish two of the movement's construction companies, HaBona in 1937, and Mishkanot in 1938, serving as chairman of the board at both.

Kelmer attended a religious teachers' seminary in Jerusalem, and graduated from the Hebrew University's law faculty.
