AKMU (; Korean: 악뮤), formerly Akdong Musician (; Korean: 악동뮤지션), is a South Korean duo consisting of siblings Lee Chan-hyuk and Lee Su-hyun signed to YG Entertainment. As prominent figures of South Korea, their musical impact in their native country has earned them numerous accolades and the honorific title "The Nation's Siblings". They are also cited as "musical prodigies" and "geniuses".

Propelled to national stardom through the second installation of K-pop Star (2012–2013), AKMU officially debuted in April 2014 with Play, a studio album solely crafted by Lee Chan-hyuk alone. It topped the Gaon Album Chart, became their first entry on Billboard, namely the Heatseekers Albums Chart and the World Albums Chart, and birthed the three titular singles, "200%", "Give Love", and "Melted". It was well received by the public and critics, having sold more than 6.9 million downloads, and was awarded Best Pop Album in the 12th Korean Music Awards. Following the release of their critically acclaimed Puberty series, consisting of Spring (2016) and Winter (2017), the sibling duo reached greater career heights with Sailing (2019) and its lead single "How Can I Love the Heartbreak, You're the One I Love", which not only topped the Circle Digital Chart, but also sold 2.5 million digital copies, following "Last Goodbye" (2017), and was the fourth single to be certified triple platinum for streaming in Korea Music Content Association history.
