A leading Asian online betting website, Dafabet has grown rapidly over the past 18 months and is now established as one of the top sportsbook brands in the world.
In 2012 Dafabet was ranked 21st in the prestigious eGaming Review Power 50 list of online gaming operators.
As part of the agreement, the Dafabet logo will feature on the home and away Villa shirts and the company will enjoy a host of sponsorship benefits.
"We're pleased to announce our partnership with Dafabet," said Villa Chief Executive Paul Faulkner.
"There is a real sense of excitement, anticipation and optimism as we look forward to the new season, building on the solid foundations we have in place.
"This will be a good and positive partnership for the Club and we are looking forward to working together with Dafabet as we continue to build and move the Club forward.
"Crucially for us, during negotiations Dafabet displayed a strong willingness to work with us in our continued support for Acorns and we look forward to progressing some ideas around that in the near future."
Dimitris Karatzas, Managing Director of Online Betting and Gaming at AsianBGE, said: "After entering the Premier League last season as international betting partners to two clubs, we saw the increased potential of becoming an official club sponsor.
"All of the team here are football mad, supporting sides from all around the world. It's no cliché to say we love, live and breathe the game with extreme passion.
"It's a very significant and proud moment for us to form such a partnership with Aston Villa, a side steeped in tradition.
"We are delighted to see Dafabet on the front of such a well-recognised shirt and to be associated with a club respected throughout the footballing world. I am sure all the fans will agree the kit looks great.
"We look forward to the new season and hope this partnership continues well into the future."
John Cruces, Head of Sponsorships at Dafabet added: "The Premier League is second to none in the world of football, simply speaking it's the most exciting and recognised league in the world.
"To be associated with one of the oldest and most successful clubs in England will help us achieve our aim of making Dafabet a household name - not just in Asia, where the majority of our players are currently from, but worldwide."
Acorns Chief Executive David Strudley said: "The ongoing support shown by the Club and fans for Acorns is immeasurable and clearly demonstrated by their efforts to include us in their discussions with Dafabet.
"We are extremely grateful to both AVFC and Dafabet in what is a crucial year as we celebrate 25 years of caring and look to a future where we can help to provide care and support to each of the 2,000 plus life-limited and life-threatened children in the region."
