Radio Barth, Electronics store building in central Stuttgart, Germany

Radio Barth was a commercial building in central Stuttgart, erected between 1964 and 1966 to plans by architect Paul Stohrer. It stood where the City Plaza office and commercial building now stands. Until 1995 it housed the music and entertainment electronics store founded by Robert Barth in 1878, one of Württemberg's oldest music shops. The building was demolished in October 2000.

The building was constructed between 1964 and 1966 according to architect Paul Stohrer's designs and served as retail space. After the original music store closed in 1995, the site was later replaced by a modern office and commercial complex.

From 1995 until the building was demolished in October 2000, the Radio-Bar occupied the premises and became an important cultural meeting place of the German hip-hop scene of that time. Before that, after the music shop's insolvency, creatives from Stuttgart's music and cultural scene moved in, among them the Kolchose, the 0711Büro and director Zoran Bihać.

The site is now occupied by City Plaza, a modern complex in downtown Stuttgart, and can be visited during regular business hours. The location is well served by public transport and within walking distance of other city attractions.

The building's story was later told in the radio documentary Lebensgefühl im Waschbeton, produced by the Stuttgart station Dasding in 2009, which gives former users of the house a voice. The title refers to the exposed-aggregate concrete of the 1964–1966 Stohrer building.
