The 54-year-old Argentine, who took over the national team in 2024 after leaving Chelsea, had originally been contracted until the end of the 2026 FIFA World Cup. His new deal extends his stay for another four years.
U.S. Soccer chief executive JT Batson said the organisation believes Pochettino is the right man to continue building the national team.
"Mauricio and his staff believe in the future of soccer in the United States and our new project allows us to build on the progress of the USMNT and the momentum of U.S. Soccer."
Pochettino guided the United States to the last 16 of this year's World Cup after an impressive group-stage campaign. The Americans finished top of their group ahead of Australia, Paraguay and Turkey, collecting six points, their highest-ever total in the men's World Cup group stage.
The USA then defeated Bosnia in the last 32 before their tournament ended with a 4-1 defeat to Belgium in the last 16.
Despite the disappointing exit, Pochettino said his confidence in the project has only grown.
"Working together with U.S. Soccer over the past two years, it has become clear to us that there is tremendous potential to make the Men's National Team program even stronger.
"The passion we experienced from the fans throughout the World Cup only strengthened our belief in what is possible here."
Pochettino has built a reputation for attacking, high-energy football during his managerial career.
He first earned widespread praise after leading Southampton to an eighth-place Premier League finish in 2013, which was the club's best league finish at the time.
He later guided Tottenham Hotspur to their first UEFA Champions League final in 2019 before winning the Ligue 1 title with Paris Saint-Germain in 2022.
After leaving Chelsea by mutual agreement in 2024 following a sixth-place Premier League finish, Pochettino accepted the challenge of leading the United States.
