The royal trio are hoping to break down the stigma surrounding mental health with their new campaign, and help people feel more comfortable discussing mental wellbeing, as well as providing the tools they need to support friends and family.
William, Kate and Harry were pictured arriving at the Olympic Park on Monday (16 May) for the official launch, the morning after they joined The Queen for her 90th birthday celebrations at Windsor Castle.
As always, Kate looked lovely, this time wearing a blue printed statement skirt and billowing white blouse, while William and Harry were smart in blazers.
Heads Together was inspired by the royals' individual work: William's work as an emergency response pilot and with homeless charities, Kate's work with young people, and Harry's work with veterans.
Heads Together will partner with various charities to raise awareness of mental health issues, and has been named 2017 Virgin Money London Marathon Charity of the Year.
In a statement, they said: "Through our work with young people, emergency response, homeless charities, and with veterans, we have seen time and time again that unresolved mental health problems lie at the heart of some of our greatest social challenges.
"The Duke and Duchess of Cambridge and Prince Harry are spearheading the Heads Together campaign to end stigma around mental health. Heads Together aims to change the national conversation on mental health and wellbeing, and will be a partnership with inspiring charities with decades of experience in tackling stigma, raising awareness, and providing vital help for people with mental health challenges."
