Both teams needed extra time to get through the quarterfinals, as Jude Bellingham inspired England past Norway, and a superb Julian Alvarez goal saw Argentina knock out Switzerland.
That means another World Cup meeting between the two arch rivals with the winner facing either Spain or France in the final on July 19.
It's a rivalry loaded across football and politics, which ignited to a new level in the 1980's, following the Falklands War between the two nations and Diego Maradona's infamous Hand of God goal at the 1986 World Cup.
Across 13 meetings, England have won six - including three at the World Cup - Argentina have won three overall - with two at World Cup alongside four draws.
England v Argentina: A World Cup rivalry
2026 will be the sixth World Cup meeting between the two teams as the most common opponent for both sides on the world stage.
England beat Argentina 3-1 in their first World Cup game in Chile in 1962, as late goals from Bobby Charlton and Jimmy Greaves secured a group stage victory at the Estadio El Teniente.
The Three Lions went up a gear four years' later, as Geoff Hurst netted a quarterfinal winner against La Albiceleste, and the game descended into chaos at Wembley Stadium with Argentina captain Antonio Rattin sent off.
That was an early trigger for what was to come, as Sr Alf Ramsey refused to let this players swap shirts with Argentina at full-time, and England went on to win the World Cup on home soil.
Argentina's revenge came in Mexico '86, in a match dominated by Maradona, following three friendlies in the intervening two decades.
Maradona famously punched the opening goal past England goalkeeper Peter Shilton before scoring a second which went on to be voted as the greatest World Cup goal of all time.
Argentina would claim the trophy and a burning rivalry caught fire on a permanent basis.
1998 and 2002's meetings centred on David Beckham, after he was sent off for kicking out at Diego Simeone in the former before crashing home a penalty to secure an England win in the latter.
Beckham's journey in between the two games was symbolic, as he went from hated figure to captain inside four years, but neither tournament ended with either Argentina or England reaching the final - that will not be the case this time.
