Elina Svitolina, Simona Halep, Serena Williams and Barbora Strycova are the final four.
They will all be in action with one of that quartet lifting the Wimbledon trophy on Saturday.
Williams only has the women’s singles to focus on now having been knocked out of the mixed doubles, where she partnered Andy Murray.
Williams will face Strycova, who knocked out Johanna Konta in the quarter-finals.
That will be the second match on Centre Court with Svitolina’s clash with Halep first up.
Svitolina said: “It feels amazing. it is the first semi-final for me.
“I didn’t expect it would happen. It is exciting and I am looking forward to it already.
“It is going to be another day it is a great opportunity to play another match here
“I really love the atmosphere and it is exciting to play on the Centre Court hopefully. It is going to be my very first time.”
