Rundfunk Berlin-Brandenburg (pronounced [ˈʁʊntfʊŋk bɛʁˌliːn ˈbʁandn̩bʊʁk] ⓘ; "Berlin-Brandenburg Broadcasting"), commonly shortened to RBB (pronounced [ˌɛʁbeːˈbeː] ⓘ; stylized as rbb), is an institution under public law (national broadcaster) for the German states of Berlin and Brandenburg, based in Berlin and Potsdam.

RBB was established on 1 May 2003 through the merger of Sender Freies Berlin (SFB) and Ostdeutscher Rundfunk Brandenburg (ORB), based in Potsdam, and is a member of the Association of PSBs in the Federal Republic of Germany (ARD).

As a result, RBB is required to treat both states equally "with respect to the regional content needs".

The public prosecutor started an investigation and Schlesinger stepped back from the office as ARD-director and rbb-director.

Since 1958, initially with a slot in ARD including nationwide transmission of the Berlin visit of John F. Kennedy, and later distributed under SFB-frequency, Abendschau reports on politics, economy, sports in Berlin and as well as news from the various districts and boroughs of the city.
