The Queen will be throwing a huge street party on the Mall in London as part of three days of official celebrations for her 90th birthday.
Every year the Queen celebrates two birthdays one for when she was born, and an official one.
This weekend the Queen has celebrated her official birthday with a huge parade called Trooping the Colour.
Today is 'The Patron's Lunch' where the Queen throws a big party for 10,000 people, including a picnic and a parade.
We want to know if you will be celebrating the Queen's birthday today?
My school had a giant picnic in our sports hall with all of the teachers and over 1000 students. It was AMAZING!

We've already had our party, and it was pouring it down! However all the children enjoyed the bouncy castle. We also had to go inside for the cake competition!
