{{Expand list|date=January 2021}}[[File:Four antennas ALMA.jpg|thumb|300px|Four of the sixty four total antennas of the ALMA radio telescope, at the [[Atacama Large Millimeter Array]] (ALMA) ]]
[[File:West arm of UTR-2 radio telescope phased array antenna.jpg|thumb|300px|West arm of the low-frequency [[Ukrainian T-shaped Radio telescope, second modification]] (UTR-2) radio telescope phased array antenna]]

This is a '''list of radio telescopes''' – over one hundred – that are or have been used for [[radio astronomy]]. The list includes both single [[parabolic antenna|dishes]] and [[astronomical interferometer|interferometric]] arrays. The list is sorted by region, then by name; unnamed telescopes are in reverse size order at the end of the list.

The first radio telescope was invented in 1932, when Karl Jansky at Bell Telephone Laboratories observed radiation coming from the Milky Way.
