Radio Bremen (pronounced [ˈʁaːdi̯o ˈbʁeːmən]), shortened to RB (pronounced [ɛʁˈbeː]) is Germany's smallest public radio and television broadcaster and the legally mandated broadcaster for the city-state Free Hanseatic City of Bremen (which includes Bremerhaven).

In 1922 the "Deutsche Stunde für drahtlose Belehrung und Unterhaltung" (German Hour for Wireless Education and Entertainment) was founded with the participation of Ludwig Roselius.

Some notable people like Loriot and Jan Böhmermann spent significant parts of their careers at Radio Bremen.

Radio Bremen produces and provides programmes for the nationwide television network Das Erste, the main national public TV channel.

The FM and TV signals (including DVB-T) are broadcast in Bremen from the Bremen-Walle Telecommunication Tower, which is operated by Deutsche Telekom.
