The Arabian Horse Association (AHA) and Region 4 provide many opportunities for you to enjoy the Arabian horse. AHA is a full-service breed association and registry for owners of Arabian, Half-Arabian and Anglo-Arabian horses.

The AHA’s Region 4 is comprised of the entire state of Oregon and Southern Idaho. Home to many of the nation’s top show horses, Region 4 is proud of its friendly members who want to share the Arabian and part-Arabian horses.

Arabian, Half-Arabian and Anglo-Arabian horses from Region 4 are among the best in the nation. Whether you are looking for a national quality show horse, an athletic sport horse, a trusty trail companion, or a backyard pet, our members can help you find that special four-legged friend.

The Region 4 Arabian Championship Horse Show is held annually in June at the Idaho Horse Park, the Pacific Northwest’s premier horse show facility located in Nampa, Idaho. We are eager to welcome back our fervent supporters who have voted this their USEF Favorite Arabian Show – THREE YEARS IN A ROW!

Barn parties, wonderful vendors and, some of the most beautiful, talented Arabian show horses in America are highlights of our annual week of fun and excitement. We hope you can attend as an exhibitor, but if not, come as a spectator and experience the unique hospitality of the Idaho Horse Park.

You will soon discover that this show is well worth the drive.

As you make your plans to qualify for Regional classes, we hope you patronize the other fine horse shows offered in Region 4 by our member clubs. We offer a pre-show as a lead in to the Championship Show in case you need additional qualifications or you just need a tune-up to be at your best.

We try to be a responsive region by supporting not only the show ring, but also the non-show events. We offer Sport Horse events, endurance rides, trail rides, scholarships and eight local clubs to meet the wants of all Arabian horse owners.
