Creamfields festival will support the Tim Parry Johnathan Ball Foundation for Peace at this year's event.
The charity runs educational programmes for young people and adults to inspire them to lead more peaceful lives.
It also works to generate toleration among social groups and reduce levels of violence, prejudice, discrimination and racism.
James Barton, co-founder and owner of Creamfields, said that the festival wanted to recognises a charity which helped young people.
"Creamfields attracts over 40,000 young people to its festival. We wanted to support an organisation that was working with young people in the area and the foundation is doing some amazing work to reduce intolerance and violence," he said.
The foundation said it was "delighted" at having been chosen by the festival. Wendy Parry, co-founder of the charity, said it would help the organisation to expand its remit.
Creamfields takes place on August 25th in Cheshire and boasts a line-up of live acts and DJs.
The Chemical Brothers, Groove Armada, Kelis, Mark Ronson and LCD Soundsystem are all playing at the event.
DJs include Carl Cox, Erick Morillo, 2ManyDJs, Ferry Corsten and Eddie Halliwell.
