Nocturne is the third EP by South Korean boy band 2AM.

It was released in November 27, 2013 with the song "Regret" as the title track.

[1] Prior to the official release of their third EP, 2AM pre-released 'Just Stay' from their third mini album 'Nocturne' on November 19, 2013.

The song 'Only You' is reminiscent of nineties K-Pop and R&B, which makes this one of the standout tracks in regard to the evolution of 2AM.

It's the last 2AM album to be released under Big Hit, before their transition back to JYP Entertainment.
