Elsa Reichmanis (born 9 December 1953 in Melbourne, Australia) is an American chemist, who was the 2003 president of the American Chemical Society. She was elected a member of the National Academy of Engineering in 1995 for the discovery, development, and engineering leadership of new families of lithographic materials and processes that enable VLSI manufacturing. She was also inducted into the National Academy of Inventors in 2020. She is currently the Anderson Endowed Chair in Chemical and Biomolecular Engineering at Lehigh University. She previously served on the faculty at The Georgia Institute of Technology. Reichmanis is noted for her research into microlithography, and is credited for contributing to the "development of a fundamental molecular level understanding of how chemical structure affects materials function leading to new families of lithographic materials and processes that may enable advanced VLSI manufacturing".
