The First Cambridge Catalogue of Radio Sources (1C) refers to the catalogue listed in the article Ryle M, Smith F G & Elsmore B (1950) MNRAS vol 110 pp508-523 "A Preliminary Survey of Radio Stars in the Northern Hemisphere".

The 1C catalogue listed about 50 radio sources, detected at 3.7 m with a fixed meridian interferometer. According to researchers at the Special Astrophysical Observatory, most of the sources from 1C were later recognized to be the effect of confusion, i.e. they were not real objects.

The survey was produced using the Long Michelson Interferometer at the Old Rifle Range in Cambridge in 1950. This device operated primarily at a wavelength of 3.7 metres, and was operated using Ryle's phase switching technique. F. Graham Smith also used the interferometer to measure the electron density in the ionosphere.

The catalogue from this survey is only informally known as the 1C catalogue.
