On 17 May 2018, he was called up to the 23-man French squad for the 2018 FIFA World Cup in Russia. On 28 May 2018, Giroud scored his 31st international goal for France during a home game against Ireland, equalling Zinedine Zidane's record, and becoming the fourth highest goal scorer of all time for the country. Giroud's inclusion in the team as a big man towering over opposing defenders was designed to create more freedom for Antoine Griezmann and Kylian Mbappé to generate offensive chances. Giroud played in all seven matches, and though he failed to register a shot on net on 13 shots, his physical presence and link-up play was credited with Griezmann and Mbappé each scoring four goals. On 30 June 2018, Giroud set up Mbappé's second goal in a 4–3 win over Argentina. In the final of the tournament on 15 July, France defeated Croatia 4–2 to win their second FIFA World Cup title.
