Cliff Williams has given up his time in the name of amateur sport for a period of more than 30 years and worked in both boxing and rugby helping young people to improve their lives through sport.
Wales coach Warren Gatland welcomed the award to Williams for all the support he has given to grass roots rugby during a lifetime as a volunteer in the sport.
"It's people like Cliff who make my job easy," said Gatland.
"By the time I get hold of players they have been through the system, the Shane Williams's and Ryan Jones's of this world all starting somewhere with someone like Cliff giving up their time to encourage them and show them the ropes.
"It's at that level that all the real hard work is done and I can't praise Cliff and the many hundreds of people like him highly enough."

Williams is now in contention for the UK Unsung Hero award made at Liverpool's Echo Arena on Sunday 14 December.
"This is a proud moment for me, but there are so many of us who volunteer our time because we love sport and who work hard for young people and I'd like to accept this award in the good name of each and every one of them," he added.
