The LeeStock Music Festival at Long Melford, near Sudbury, has been awarded the title of Best Festival in Suffolk.
It received the title from the East Anglian Festival Network, a body working on behalf of the organisers of more than 600 festivals, fairs and other events across the region.
LeeStock takes place at Melford Hall in Long Melford every year in memory of Lee Dunford, a 21-year-old musician from Sudbury who died of a brain tumour in 2006.
To date more than £60,000 has been raised in Lee's name for the Willow Foundation, a national charity that gives special days to seriously ill young adults.
LeeStock festival co-organiser Andy Piper said: "It's a real honour to receive this award from the East Anglian Festival Network when there are so many great festivals in the region.
"We all work incredibly hard on LeeStock, with the festival getting bigger and better every year which is all down to our loyal audience.
"We're so grateful to be involved with the festival which is not just about a great weekend but about raising awareness for the amazing work of the Willow Foundation and the enduring memory of Lee Dunford."
The festival grew from humble beginnings at Glemsford Social Club with a 150 capacity audience featuring local bands.
It is part of a number of events that aim to raise the profile of the Willow Foundation and raise money for them including a pub crawl, a football match, and a Twenty20 cricket match.
As it grew in popularity it moved to the White Horse in Sudbury and featured well known indie artists Dodgy and Mark Morriss of the The Bluetones.
By 2013 it was so popular it moved to nearby National Trust property Melford Hall.
Since then it has welcomed big-name acts including Feeder, Rebecca Ferguson, Pixie Lott, The Wildhearts, StarSailor, Republica, Reef, Scouting For Girls, Lightning Seeds, and The Feeling.
Tickets have sold out well in advance for the last three years and the event has now donated more than £175,000 to the Willow Foundation.
Tickets for LeeStock Music Festival 2020 are now on sale at the LeeStock website.
Band applications are open via email.
