Comedy, craft workshops and live music will provide an "amazing tribute" to an 18-year-old teenager who died suddenly.
Volunteers from Emma's Trust have invited people from across the county to join them at Emma's Day in Chipping Norton on Sunday.
The funday has been held annually for three years in memory of teenager Emma Curtis-Smith, who died suddenly in June 2005.
Ms Curtis-Smith, 18, was an asthmatic who suffered a collapsed lung while watching her boyfriend on parade at Sandhurst.
The injury led to a heart attack and the former Chipping Norton School pupil died in hospital three days later.
After her death, family and friends formed Emma's Trust in her name.
The charity has handed out more than £30,000 in grants to help young people make the most of their talents.
Ian Nolancorr, one of the charity’s trustees and a cousin of Emma, said: "Emma's family and friends have been astounded by the success of the trust — it continues to be an amazing tribute to her. The trust is important because it helps young people achieve all they are capable of."
Sunday's event will see people who have been helped by the trust demonstrate their talent in the town.
A farmers market, rugby workshop and climbing wall will complement a five-a-side football tournament, dance workshops and live music.
Comedian Rhona Cameron will host a fundraising evening concert at The Theatre.
Mr Nolan said: "The day always has a real diverse mix of young and old together, and there is always an excited atmosphere."
Emma's Day will run from 8am to 7pm, when the concert starts. To find out more visit emmastrust.com
