{{Short description|none}} {{Use dmy dates|date=October 2024}} This is a '''list of notable interstellar radio messages''' (IRMs) transmitted from Earth. Many of these were sent in the aim of searching for extra-terrestrial intelligence (SETI), and are often called 'active SETI' or 'METI' (Messages to Extra-Terrestrial Intelligence) projects.

Whilst not an interstellar message, it is also worth mentioning The Morse Message (1962),<ref>[http://www.lightspeedmagazine.com/nonfiction/you-never-get-a-seventh-chance-to-make-a-first-impression-an-awkward-history-of-our-space-transmissions/ An Awkward History of Our Space Transmissions]</ref> which was sent to Venus.
