"Safe and Sound" is a song by American indie pop duo Capital Cities, written and produced by band members Ryan Merchant and Sebu Simonian. The song was released as a single on January 6, 2011 and first appeared on their debut EP Capital Cities (2011), later serving as the lead single from their debut studio album, In a Tidal Wave of Mystery (2013). "Safe and Sound" became the duo's breakout hit, peaking at number eight on the United States Billboard Hot 100 and achieving commercial success in several other territories. Three music videos were produced for the single, with the third video, directed by Grady Hall and set in the Los Angeles Theatre, later being nominated for Best Music Video at the 56th Annual Grammy Awards.

"Safe and Sound" is a synthpop and dance-pop song, and was written and produced by Capital Cities members Ryan Merchant and Sebu Simonian. It features a prominent trumpet line, which was only incorporated into its production after eight previous takes of the song.

The first music video for "Safe and Sound" was self-produced and edited by the band and uploaded to their official YouTube account on February 24, 2013, and features alternating historical film clips of dancing and war from the last century generally arranged in chronological order. Another video, directed by Jimmy Ahlander, was released on October 21, depicting the duo being led through a junkyard by a monk.

The third and most well-known video for the song was directed by Grady Hall and released on April 25, 2013. The video is set in the Los Angeles Theatre and depicts Capital Cities performing on stage as dancers of all types (1940s swing dancers, 1970s roller disco skaters, 1990s hip-hop dancers, etc.) emerge from pictures on the wall and film clips from different time periods in the theater's history come to life and compete in dance-offs. It received a nomination in the Best Music Video category at the 56th Annual Grammy Awards.
