Uma Chowdhry (1947 – January 7, 2024) was an American chemist whose career was spent in research and management positions with E. I. du Pont de Nemours and Company.

After two years with Ford Motor Company, she entered the Massachusetts Institute of Technology (MIT) where she earned a Ph.D. in materials science in 1976.

In 1987 she led DuPont's research effort in ceramic superconducting materials and developed a program that generated over 20 patents and 50 publications.

[1][2] In 2006 she became senior vice president and global chief science and technology officer of DuPont,[1][2][14] responsible for the company's core research programs and the DuPont "APEX" portfolio of research programs, including basic chemistry, materials science and biotechnology.

[16] In response to contamination of Ohio river caused by perfluorooctanoic acid (PFOA, also known as C8), the key ingredient in Teflon, and subsequent cases of cancer and other medical issues, when asked if this C8 chemical could be responsible for babies born with deformities in 2 out of 8 former DuPont women employees, Ms. Uma responded "In the realm of scientific facts, this is not considered a statistically significant sample.

She was elected a member to the National Academy of Engineering in 1996 for the application of advanced ceramic technologies to novel catalyst structures, large-scale chemical synthesis, and multilayer electronic circuit manufacture.
