The Cambridge Interferometer was a radio telescope interferometer built by Martin Ryle and Antony Hewish in the early 1950s to the west of Cambridge (between the Grange Road football ground and the current Cavendish Laboratory). The interferometer consisted of an array of 4 fixed elements to survey the sky, and produced the 3C catalogue of radio sources at 178 MHz, which includes some of the most interesting astronomical objects known. The telescope was operated by the Radio Astronomy Group of Cambridge University.

Martin Ryle and Antony Hewish received the Nobel Prize for Physics in 1974 for this and other related work.
