The North American Tree Climbing Championship (NATCC) provides a competitive but educational opportunity for working arborists in North America to demonstrate and exchange new climbing techniques and equipment as well as safe work practices. The NATCC provides positive public exposure for the profession in that region of the world.

The winners of this event represent North America at the annual International Tree Climbing Championship.
