Gnabry was born in Stuttgart, Baden-Württemberg to an Ivorian father and a German mother. In his youth, Gnabry was a talented sprinter but ultimately chose football over athletics.

On 4 November 2016, Gnabry received his first call-up to the German senior team. Seven days later, he scored three goals on his debut in a 2018 World Cup qualifier against San Marino in an 8–0 away win. On 9 October 2019, during a 2–2 friendly international draw with Argentina, Gnabry became the fastest player to reach 10 goals for the nation, doing so in his 11th appearance and beating Miroslav Klose's record by 2 games. On 19 November 2019, he scored three goals in the 6–1 victory against Northern Ireland. It was his second hat-trick in his international career.

On 19 May 2021, he was selected to the squad for the UEFA Euro 2020. In November 2022, he was named in the 26-man squad for the 2022 FIFA World Cup in Qatar.
