"Dangerous Night" is a song recorded by American rock band Thirty Seconds to Mars, featured on their fifth studio album America.

It marked a strong departure from much of the band's previous work as it incorporates a softer sound as well as elements from electronic dance music.

After the first verse, characterized by electronic dance beats, the pre-chorus follows, leading to an anthemic chorus featuring prominent use of guitars, drums and synths.

Randy Holmes from ABC Radio called it "more of a personal song" compared to the band's previous works, although he noted that it retained its euphoric and anthemic nature.

[6] Nina Braca from Billboard acknowledged the band's stylistic change, considering the song a departure from the group's previous hard rock sounds.

[8] Thirty Seconds to Mars performed the song live for the first time at The Late Show with Stephen Colbert on January 25, 2018.
