"Let's Go" is a song by Dutch disc jockey and producer Tiësto with vocals from Swedish synth-pop duo Icona Pop, who co-wrote the song with Tiësto, Oscar Holter, Marcus Sepehrmanesh, Alx Reuterskiöld and Karl-Ola Solem Kjellholm.

It was released on 13 May 2014 by PM:AM Recordings as the third single from Tiësto's fifth studio album, A Town Called Paradise.

"Let's Go" was featured in the soundtracks of numerous films or TV shows, such as Night at the Museum: Secret of the Tomb, Pitch Perfect 2, Vacation, Sisters, Red Band Society, Hawaii Five-0 or the teaser trailer for the 2018 animated film Teen Titans Go!

[citation needed] Tiësto declared about the song : "It's a very energetic track with so much energy in it.

"[2] Nolan Freeney of Time considers that "Tiësto’s production doesn’t grind quite as hard as the singers’ past hits, and the added acoustic guitars feel like a blatant effort to capitalize on the success of Avicii’s “Wake Me Up!” but all of that is forgivable: the track’s highs are euphoric enough to get the job done.
