Lewis Levitzki Lorwin (December 4, 1883 – June 6, 1970) was an American economist, economic planner, and labor historian of Russian-Jewish origin.

He was suspended from his position for his writings on the mining industry, but later reinstated with support from the American Association of University Professors.

At Brookings, Levine changed his name to Lewis L. Lorwin, which his biographers have said was a choice to hide his Russian-Jewish origins.

[1] While working for Brookings, Lorwin established ties to the Frankfurt Institute for Social Research.

He was criticized by Red Scare conservatives for remarks he had made in the 1930s and resigned his position in 1952.
