Helmut Rauch (22 January 1939 – 2 September 2019) was an Austrian physicist. He was especially known for his pioneering experiments on neutron interference.

Rauch studied Physics at Vienna University of Technology and worked at the {{ill|Institute of Atomic and Subatomic Physics|de|Atominstitut|vertical-align=sup}} there. He was also affiliated with the Forschungszentrum Jülich and the Institut Laue-Langevin in Grenoble.

In his Nobel Prize Lecture in 2022, Anton Zeilinger spoke about what his mentor, Helmut Rauch taught him. In a part of his speech, he said: "From my mentor, I learnt that you can have ideas. Which are wrong in a sense that the arguments are wrong but the idea is right. That intuition can be much stronger than a logic argument".{{Cite web |title=The Nobel Prize in Physics 2022 |url=https://www.nobelprize.org/prizes/physics/2022/zeilinger/lecture/ |access-date=2023-01-04 |website=NobelPrize.org |language=en-US}}
