Goodwin Robert Greenberg (June 23, 1918 —May 15, 2005) was an American chemist.

Greenberg was born in Danube, Minnesota on June 23, 1918. He attended the University of Minnesota where he received his B.A (1941), M.S. (1942), and Ph.D. (1944) in biochemistry. Greenberg's research fields included purine biosynthesis, enzymology, and molecular genetics. From 1944-1946, Greenberg was a fellow at the University of Utah, where he worked on a chemical warfare project and the anemia of infection. In 1946, Western Reserve University hired Greenberg to develop the new Department of Biochemistry, where his research focused on the biosynthesis of purines. He was promoted to Assistant Professor (1948) and Associate Professor of Biochemistry (1954). In 1957, he received the American Chemical Society's Paul Lewis Award in Enzyme Chemistry. In February 1957, Greenberg was appointed professor at the University of Michigan Medical School's Department of Biological Chemistry.

In 1967, his research interests turned to studying bacterial viruses, studying the roles of dCMP hydroxymethylase and dTMP synthetase. He also became involved with studying bacterial genetics, researching the thymidlate synthesase in E. coli and phage ?thyA hybrids. In the 1970s, his research turned towards molecular genetics, when he worked on synthesizing deoxyribonucleotides in phage-infected cells, ultimately conducting research on membrane biochemistry with Nobel laureate Har Gobind Khorana at MIT from 1974-1975. Greenberg continued to work in molecular genetics through his appointment as Professor Emeritus in 1988 until his death on May 15, 2005.

Dr. Greenberg was an active faculty member and a member of the American Society of Biological Chemists and American Society for Microbiology.
