Around 12,000 Year Six students will have the opportunity to hear the prince's speech tomorrow as he takes to the stage alongside Malala Yousafzai, Ellie Goulding, Dizzee Rascal, Jennifer Hudson, former US vice president Al Gore, Harry Potter star Evanna Lynch and former England football player Gary Neville, amongst others.
The We Day event has been organised by charity Free The Children, to encourage young people to volunteer and take action on social issues around the globe.
The event is free to attend, but students have had to earn their place there by undertaking one local and one global charitable act as part of the year-long We Day programme, which Free The Children runs through schools.
Prince Harry's speech is sure to draw on personal experience, as his own charities Sentebale and The Royal Foundation of The Duke and Duchess of Cambridge and Prince Harry, are both involved with helping children and young people in the UK and overseas to build their skills, confidence and aspirations.
The event will be live streamed tomorrow on AOL UK.
