Sarah C. Eno is an American experimental particle physicist at the University of Maryland, College Park, where she is a professor of physics and UMD Distinguished Scholar–Teacher.

She has participated in several large experimental collaborations in high-energy physics, including the AMY experiment at the Japanese TRISTAN particle accelerator, the DØ experiment at Fermilab in the US, the Collider Detector at Fermilab, and the Compact Muon Solenoid experiment at the Large Hadron Collider in France and Switzerland.

She studied physics as a graduate student at the University of Rochester, earning a master's degree there in 1986 and completing her Ph.D. in 1990.

[2] In 2009, Eno was elected as a Fellow of the American Physical Society (APS), after a nomination from the APS Division of Particles and Fields, "for contributions in particle physics involving electroweak parameters, precision electroweak measurements, and physics beyond the Standard Model at the Tevatron".

[3] She was named to the 2021 class of Fellows of the American Association for the Advancement of Science.
