Morris David Waldman (May 1, 1879 – September 7, 1963) was a Slovakian-born American rabbi and social worker.
He served as rabbi of Temple Anshe Emeth in New Brunswick, New Jersey, after which he began working in social welfare.
He briefly worked as assistant director of the civilian department of the American Red Cross in Washington, D.C., in 1917.
He introduced a number of innovations in social work across the country, including the District Service Plan in Boston that focused on family units instead of individual family members, a planned parenthood clinic in Detroit, and Jewish education bureaus that were based on community control.
He played a critical role in implementing a human rights provision in the United Nations charter.
However, he unsuccessfully attempted to bring the Zionists and non-Zionists to an agreement at the American Jewish Committee and he later favored the establishment of Israel.
