Template:Short description Template:Use British English Template:Use dmy dates

Japan Radio Network (JRN; Template:Langx) is a Japanese commercial radio network run by TBS Radio in Tokyo, owned by TBS Holdings (which is a part of the major conglomerate Mitsui Group). Established on 2 May 1965, JRN is made up of 35 regional affiliates, including four full-time affiliates and 31 stations that are dual-affiliated with the rival National Radio Network (NRN) as a part of "cross-network" practice in Japan.

Out of the 35 regional affiliates, 21 JRN stations are connected with a JNN station (ex. RCC Radio & RCC Television), with some operating the affiliate as a separate radio subsidiary (ex. MBS Radio & CBC Radio), 10 are connected with a Nippon TV (NNN/NNNS) affiliate (ex. KRY Radio & KRY Television), 1 as a radio subsidiary of Asahi Broadcasting Corporation (whose TV subsidiary is under ANN, and is a former JNN affiliate), 1 connected to a dual NNN/NNS & ANN affiliate (Fukui Broadcasting), and 2 that are operating as a radio-only station (RFC & WBS). Nishinippon Hōsō (RNC), initally an NRN-only station since its creation in 1965, became the last radio station to join JRN in October 1997.

Despite not being a member of the network, independent station Radio Kansai airs some JRN programming, including the late night JUNK comedy line up. Also, NRN-only core station OBC Radio Osaka also airs some JRN programming, including the BRAND NEW MORNING radio program.
