Morgan Cole Wallen (born May 13, 1993) is an American country singer. He competed in the sixth season of The Voice, originally as a member of Usher's team, but later as a member of Adam Levine's team. After being eliminated in the playoffs of that season, he signed to Panacea Records, releasing his debut EP, Stand Alone, in 2015.

In 2016, Wallen signed to Big Loud, releasing his debut album, If I Know Me, in 2018. The album includes the singles "Up Down" featuring Florida Georgia Line, "Whiskey Glasses", and "Chasin' You". If I Know Me reached No. 1 on the Billboard Top Country Albums chart. Wallen's second album, Dangerous: The Double Album, was released in January 2021, and in February 2021 became the only country album in the 64-year history of the Billboard 200 to spend its first seven weeks at No. 1. It spent its first ten weeks at number one, the first album to do so since Whitney Houston's Whitney in 1987. The album included singles "More Than My Hometown", "7 Summers", and "Wasted on You".

His third studio album, One Thing at a Time (2023), topped the Billboard 200 for 19 non-consecutive weeks, with all of its 36 tracks entering the Billboard Hot 100. This broke the record for most songs by an artist on the chart at one time. The single "Last Night" peaked atop the Hot 100 in 2023, becoming Wallen's first single to do so, and later set the record for the most weeks at number one for a non-collaboration song (sixteen weeks), as well as tying for the second most weeks of all time and topping the year-end chart. He has received several awards including an Academy of Country Music Award and fourteen Billboard Music Awards. He won Entertainer of the Year at the 58th Annual Country Music Association Awards.
