Jan Aleksander Rajchman (London,10 August 1911-1 April 1989) was an American electrical engineer and computer pioneer. He received the Diploma of Electrical Engineering from the Swiss Federal Institute of Technology in Zurich in 1935, and became a Doctor of Science in 1938.

Rajchman emigrated to America in 1935. He joined RCA Laboratory directed by Vladimir K. Zworykin in January 1936.

He was a prolific inventor with 107 US patents among others logic circuits for arithmetic. He conceived the first read-only memory, which was widely used in early computers. He conceived and developed the selectively addressable storage tube, the ill-fated Selectron tube, and the core memory.

He was a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), and a member of the National Academy of Engineering. He is also a member of Sigma Xi, the Association for Computing Machinery (ACM), the Physical Society, the New York Academy of Sciences, and a Fellow of the American Association for the Advancement of Science and the Franklin Institute. He received the 1960 IEEE Morris N. Liebmann Memorial Award andthe 1974 IEEE Edison Medal "For a creative career in the development of electronic devices and for pioneering work in computer memory systems."
