"Dangerous" is a song written and performed by British singer–songwriter Sarah Joyce, known by her stage name as Rumer, for her third studio album Into Colour (2014).

Joyce explained that "Dangerous" was about her fear of re-entering the music industry following bipolar disorder, post-traumatic stress disorder and ADHD, only translated to a love song: "I had so much resistance to going back into writing and performing publicly again that I realised I wasn't going to be able to break through it until I literally wrote a song about the resistance itself.

"[8] Tom Ingham praised Joyce's vocal performance as her "most colourful and charged" to date.

[4] The Observer critic Paul Mardles, labeling most of Into Colour as "flat" and "forgettable," found "Dangerous" to be the album's most memorable track for its disco style.

[9] Writer Paul John, however, criticized it for being a "slightly dishonest representation of the remainder of the album," but nonetheless called it "a wonderful song in and of itself.
