Louis Benjamin Heller (February 10, 1905 – October 30, 1993) was an American lawyer and politician who served three terms as a U.S. congressman from New York from 1949 to 1954.

His parents had emigrated from Romania just a few years before the birth of their first child, a daughter named Freida.

He served as a special deputy assistant attorney general for cases of election fraud from 1936 until 1946.

He was elected as a Democrat to the 81st United States Congress, to fill the vacancy caused by the death of John J. Delaney, and was re-elected to the 82nd and 83rd United States Congresses, holding office from February 15, 1949, until his resignation on July 21, 1954.

Heller resigned from Congress to become a Judge of New York City's Special Sessions Court, where he served until 1958.
