The two best teams in women's football will collide when the US and Germany meet at the Olympic Stadium in Montreal.
How to watch
Live coverage of USA v Germany will be available live on BBC Two with kick-off scheduled for 12am (BST) on Wednesday 1 July.
The US continued their amazing record in this competition with a 1-0 win over China on Saturday 27 June, extending their remarkable run of having reached the semi-final stages in each of its seven instalments. As their quarter-final win came a day earlier than that of their opponents, Jill Ellis's side could start the fresher of the two. European champions Germany laboured in their last-eight meeting with France, needing a late equaliser from the spot from Celia Sasic to force extra time. A 5-4 win on penalties saw the top-ranked team in women's football progress. The US enjoyed a simpler evening against China and have had a slightly easier route to the final four, easing past Colombia in the first knock-out stage.
USA have not conceded since the group stage and have let just one in during the entire campaign, against Australia. That resolve will be tested against the Germans, who have netted 20 so far this tournament.
These two sides have dominated women's football on the international stage. Both have two World Cups to their name, with the US lifting two of the first three in campaigns where they beat Germany in the semi-finals along the way in 1991 and 2003.
What they said
USA coach Jill Ellis: "We're thrilled to be in the semi-finals and playing a tremendous opponent in Germany, which we haven't faced in, I think, a couple of years.
"Obviously they are a terrific team and I think it's going to be a fantastic match. We're two great teams worthy of a semi-final match up."
Germany defender Annike Krahn: "The crowd will definitely be against us and cheer on USA loudly. But that motivates us even more.
"The American playing style is completely different to that of the French. We all know that we have to be present from the first minute.
"With USA, a strong opponent awaits us. We've had some really tough games already – it also showed us that we can compete against strong sides. It's definitely a positive thing."
Germany midfielder Dzsenifer Marozsan is a doubt for Wednesday's match after suffering an injury to her left ankle. Despite the knock, the FFC Frankfurt star came off the bench during her side's 1-1 draw with France in the quarter-final, converting the fourth penalty for the Germans and helping them into the final four.
