Morris Michael Edelstein (February 5, 1888 – June 4, 1941) was a Polish-born Congressional Representative and lawyer from the state of New York, serving from 1940 to 1941.

Edelstein was elected as a Democrat to the Seventy-sixth Congress to fill the vacancy caused by the death of William I. Sirovich.

Edelstein's last speech was a response to Mississippi Representative John Elliott Rankin, widely described as an anti-Semite who advocated peace with Nazi Germany.

Rankin had just delivered a House floor speech accusing "international Jewish brethren" of trying to drag America into World War II.

... All men are created equal, regardless of race, creed or color, and whether a man be Jew or Gentile, he may think what he deems fit."
