They'll face either England or Argentina in the final this Sunday.
England and Argentina will renew their rivalry tonight, with a place in Sunday's World Cup final on the line.
England haven't made the showpiece since their 1966 triumph on home soil - and will need to get past the defending champions in Atlanta.
Tonight's game could also see Argentina captain Lionel Messi face the English for the first time.
Kick off is at 8pm Irish time.
Last night, Spain booked their place in the decider with a 2-0 win over France in Dallas.
Mikel Oyarzabal converted a first-half penalty, with Pedro Porro doubling their lead after the break.
Spain's unbeaten run in international football has now stretched to 37 games.
