"On Top of the World" is a song by American rock band Imagine Dragons for their major-label debut extended play Continued Silence (2012), where it appears as the third track. The song also appears on their debut studio album Night Visions (2012) as the fifth track. "On Top of the World" was released digitally as a single on March 18, 2013.

"On Top of the World" primarily features guitar and piano instrumentation, with vocals performed by lead singer Dan Reynolds. Originally published in the key of C major, the song itself expresses a celebration of accomplishment for the band after striving for years to become successful. The song itself incorporates the chord progression F-C-G-Dm in the chorus, with the pre-chorus using Am and G to create a different break in the song. The song "On Top of the World" is found to be a positive, upbeat track, unlike other songs found on Night Visions, including "Bleeding Out" and "Hear Me".

The song is built on a sample of minimalist composer Steve Reich's "Clapping Music" from 1972.

Imagine Dragons performed the song live on the Australian version of The X Factor in 2013.

"On Top of the World" was licensed for inclusion on the soundtrack of EA Sports game, FIFA 13. The band, longtime fans of the FIFA video game series, reacted positively to its inclusion in the game and stated that it would be "a lot of fun hearing the track play while we are doing bicycle kicks and screaming at the screen." It also served as the opening theme of the short-lived CBS comedy series Partners. "On Top of the World" was performed by the PS22 Chorus during Barack Obama's second United States presidential inauguration. It also featured in Konami video game Pro Evolution Soccer 2013 as well as being used in a Samsung Galaxy Note 8.0 advert. It was also featured in the film The Incredible Burt Wonderstone several times.
