The logo, which is a shamrock consisting of three horse shoes, was developed by Horse Sport Ireland as part of a major drive to market Ireland's equestrian teams to sponsors and the general public.
Horse Sport Ireland Chairman Joe Walsh said that the new concept had been developed over the past year by HSI to create a single identity for Irish teams across all of the FEI disciplines of show jumping, eventing, dressage, para-equestrian, carriage driving, endurance, reining and vaulting.
The launch was a new beginning for the sport in Ireland. "We have outstanding riders in this country and with top class coaches and structures in place we can take on the world. It is time for people to get behind our riders, our horses and Team Ireland Equestrian," he said.
"Last year we had 480 riders who represented Ireland in international competition with huge success and I believe that our riders, breeders and owners deserve more credit for their achievements on the world stage," he said.
"However, we cannot take a piecemeal approach, we need a focused, relentless marketing campaign with a professional back up service," he added.
"While riders on all squads, from ponies up to and including our studbook teams will be provided with specially embroidered kit, supporters will also be able to purchase Team Ireland Equestrian leisure wear and rugs.
"Horseware and Tom McGuinness have been supporting Irish teams for years and we are delighted to be working with them. They are an Irish owned company that has taken on the world and they are the perfect partners for this project," he said.
Walsh said that Horse Sport Ireland is now in the marketplace for a commercial sponsor for Team Ireland Equestrian.
"Our target is to bring in a major corporate sponsor from outside of equestrian sport who can help fund our programmes but also work with us to build the profile of our teams, our riders and our horses in the lead up to London 2012," he said.
He said that London 2012 would provide a unique opportunity for the Irish teams to win medals with climatic conditions in our favour and no travel burden on our horses.
"We need to build the commercial credibility and profile of our sport and the new logo is an important step in that process," he said.
The new Team Ireland Equestrian initiative also encompasses a new Facebook page (Team Ireland Equestrian) which already has more than 1400, a new microsite and a twitter page, teamirlEq.
