The Historical-3Dimensional-Hunting International Archery Association (HDH-IAA) is an international organization dedicated to developing and promoting archery. It brings archers together through a worldwide community and organizes competitions across historical archery and 3D archery disciplines. Its events include continental and European championships, world-level competitions, and the 3D ARChallenge, with activities hosted in countries including Malaysia, Italy, and Croatia.

HDH-IAA provides information about upcoming and past events, competition schedules, locations, categories, and results. News updates and photo galleries help participants and supporters follow competitions, including championship team finals. The association also offers guidance for people interested in organizing an HDH-IAA competition, alongside information about its vision, mission, and future strategic plans.

Archers can register for an account to join the community and access the competition system. HDH-IAA supports members through its website and official mobile app, available on the App Store and Google Play. It also provides payment support and channels for reporting bugs or sharing ideas, helping participants stay informed and connected with international archery events.
