Karl Mark Cooper helped found the +me support group in May 2008, and it is based at The Core, County Way.
A trustee of +me, David Allen, of Gawber Road, said Karl deserved the award for going 'the extra mile' to help people living with HIV.
He said: "He set up the group with a vision to transform Barnsley's response to HIV, providing fresh thinking, expertise and practical resources.
"The organisation +me champions the rights of people living with HIV and campaigns for change.
"He believes in a world in which people living with HIV are treated as equal with respect, dignity and receive the highest standards of care."
Karl has provided training to several hundred students at the college and wider community which David said has enhanced people's understanding of the facts about HIV and living with HIV in Barnsley.
He added: "He continues his work at '+me' for the eradication of HIV related stigma and discrimination."Karl Cook, an employee for +me is also championing Karl Cooper's work.
He said: "Over the last few years Karl and his team of volunteers support around 104 people living with or affected by HIV, often going that extra mile manning information stands or deliver training throughout Barnsley."
