Mullard Radio Astronomy Observatory (MRAO) adalah rumah bagi sejumlah besar teleskop radio sintesis aperture, termasuk One-Mile Telescope, 5-km Ryle Telescope, dan Arcminute Microkelvin Imager. Radio interferometri dimulai pada pertengahan 1940-an di pinggiran Cambridge, tetapi dengan dana dari Dewan Penelitian Ilmu Pengetahuan dan sumbangan sebesar £ 100.000 dari Mullard Limited, pembangunan Observatorium Mullard Radio Astronomy dimulai di Lord's Bridge, beberapa kilometer ke barat dari Cambridge. Observatorium ini didirikan di bawah Martin Ryle dari Radio-Astronomy Group of the Cavendish Laboratory, University of Cambridge dan dibuka oleh Sir Edward Victor Appleton pada tanggal 25 Juli 1957. Kelompok ini sekarang dikenal sebagai Cavendish Astrophysics Group.

Situs ini terletak di Lord's Bridge, Cambridgeshire pada bekas fasilitas penyimpanan persenjataan, sebelah jalur kereta api Cambridge-Bedford. Digunakan untuk membentuk bagian utama dari "5km" radio-teleskop dan Cambridge Low Frequency Telescope Sintesis.
