Few sporting events produce shockwaves quite like the FIFA World Cup. Every four years, football’s greatest nations arrive believing they can conquer the world, only for some to leave stunned by opponents few expected to challenge them.
The biggest World Cup upsets have become part of football folklore because they remind supporters that reputation means little once the whistle blows. Giant-killers have emerged from every continent, rewriting World Cup history with performances fueled by belief, discipline and courage.
From amateur squads defeating professionals to reigning champions crashing out against underdogs, these unforgettable World Cup upsets have shaped the tournament’s legacy.
What Makes One of the Biggest World Cup Upsets?
Not every surprise result deserves legendary status. The biggest World Cup upsets usually combine several factors. A heavily favored team loses. The underdog has little expectation of success. The result changes the tournament dramatically.
The victory leaves a lasting mark on World Cup history. These matches continue to be remembered decades later because they proved football remains gloriously unpredictable.
10. Saudi Arabia 2-1 Argentina (2022)
When Argentina arrived in Qatar, they were unbeaten in 36 matches and among the favorites to lift the trophy.
Lionel Messi gave the South Americans an early lead from the penalty spot, and many expected the goals to continue.
Instead, Saudi Arabia produced one of the finest second-half displays ever seen from an underdog.
Saleh Al Shehri equalised before Salem Al Dawsari curled home a spectacular winner that stunned the football world.
Argentina eventually recovered to win the tournament, but this remains one of the biggest World Cup upsets because nobody saw it coming.

7. Algeria 2-1 West Germany (1982)
Few believed Algeria could trouble two-time champions West Germany.
Instead, Rabah Madjer and Lakhdar Belloumi inspired a sensational victory.

More than 70 years later, it remains one of the greatest World Cup upsets ever recorded.

Argentina possessed Lionel Messi, Sergio Aguero and Angel Di Maria. Croatia had quality too, but few expected such complete domination.

2. Germany 1-2 North Macedonia (World Cup Qualifying, 2021)
Although this result came during World Cup qualification rather than the finals, it deserves mention because of its historical significance.

North Macedonia ended that remarkable run with an unforgettable victory.
