97.3 Forth One is a Scottish radio station, broadcasting to Edinburgh, The Lothians and Fife including other areas of East Central Scotland and based in Forth Street in Edinburgh’s city centre. The station plays a variety of music, mainly Top 40, but older tunes are also inserted into the playlist. The station is owned & operated by Bauer Radio and forms part of Bauer's Place Network of stations.

Since September 2008, Forth One and all Bauer-owned FM stations in Scotland air evening and overnight programming from Clyde 1 in Glasgow.

Radio Forth was launched on 22 January 1975 by current chairman Richard Findlay. His opening speech included "This, for the very first time is Radio Forth". Steve Hamilton was the first on-air presenter, hosting the breakfast show.

In 1990, Forth was forced to create a new station on its AM frequency. Before this, Radio Forth was broadcast as a single station on both FM and AM frequencies. The FM station was renamed Radio Forth RFM (later simplified to Forth FM) with Donny Hughes broadcasting the first Breakfast Show from the newly revamped Studio F in Forth House. The new AM station became "Max AM" which was later renamed Forth AM to match its sister station.
