Evolve is the third studio album by American pop rock band Imagine Dragons, released on June 23, 2017, by Kidinakorner and Interscope Records. After the release of their previous album Smoke + Mirrors (2015) and its respective world tour, a self-imposed hiatus for 2016 and cryptic messages from the band through their social media gained anticipation for their third album; it was finally announced on May 9, 2017, along with the initiation of its pre-order. In comparison to Smoke + Mirrors and their 2012 debut Night Visions, frontman Dan Reynolds called the album an "evolution" for the band.

Imagine Dragons are an American pop rock band formed in 2008, based in Las Vegas, Nevada, and currently consisting of lead singer Dan Reynolds, guitarist Wayne Sermon, bassist Ben McKee and drummer Daniel Platzman.

Rolling Stone named "Radioactive", which held the record for most weeks charted on the Billboard Hot 100, the "biggest rock hit of the year". MTV called them "the year's biggest breakout band", and Billboard named them their "Breakthrough Band of 2013" and "Biggest Band of 2017", and placed them at the top of their "Year in Rock" rankings for 2013, 2017, and 2018.
