KBS Radio 2 (Korean: KBS 2 라디오; also known by its nickname Happy FM) is a K-Pop, classical music, and entertainment network of the Korean Broadcasting System. Opened in 1933 on AM Radio, the network began utilising FM Radio frequencies 67 years later for a clearer audio reception.

Radio 2 operates daily from 5:00 am to 3:00 am of the following day. National programs originate from Seoul, with regional opt-outs as well as rebroadcasts of selected KBS 2FM programs are aired across local stations operating on FM and, if applicable, AM radio.
