As of 2023, AC/DC had won one Grammy Award. The band’s victory came at the 52nd Annual Grammy Awards, held in 2010, when “War Machine” won Best Hard Rock Performance.
“War Machine” appears on Black Ice, AC/DC’s 2008 studio album and the group’s first album of new material in eight years. The Grammy win recognized the band’s performance rather than awarding the album itself. AC/DC had been nominated several times before and after that victory but did not turn those nominations into additional wins by 2023.
The band received nominations for songs and albums including “Highway to Hell,” “Moneytalks,” The Razor’s Edge, “Rock N Roll Train,” Black Ice, and Power Up. Later nominations helped keep AC/DC’s Grammy total visible, but nominations are not counted as awards won.
This is why totals of two, three, or four are incorrect for the question’s 2023 cutoff. The Recording Academy’s artist listing records one win and ten nominations. The wording “as of 2023” also matters: it fixes the time period rather than asking for an eternal career total.
