Daniel Radcliffe is "an inspiration to sexual minority youths"
The 21-year-old actor will be honoured by The Trevor Project - an anti-suicide/support group for gay, lesbian, bisexual and transgender teenagers - with their Hero Award at a ceremony in New York in June to recognise his work with the organisation.
Daniel - who started working with the group two years ago - said: "It`s fantastic. The fact that they think of what I`ve done by promoting awareness of the Trevor Project itself and the issues that it works to promote and help is a great honour.
"I think that out of everything that I`ve done so far in my career, I think this is absolutely one of the most important, if not the most important, thing that I`m associated with."
The `Harry Potter` star - who previously appeared in a public service announcement (PSA) for the Trevor Project`s 24-hour help line - also paid tribute to the 160 volunteers and counsellors at the facility.
He said: "The people that are doing the heroic things are the people answering phones 24 hours a day in the Trevor call centres."
The Trevor Project was founded in 1998 by filmmakers James Lecesne, Peggy Rajski and Randy Stone.
Previous recipients of the Hero award include actor Nathan Lane, actress Vanessa Williams and `Milk` screenwriter Dustin Lance Black.
