Hunters are a bit of a mishmash of different ideas and character types, so that's a tough question to answer. Here are a few notable examples though.
With pets (BM?):
Rexxar (and
Misha)
Nathanos Marris (now Blightcaller) Without pets (MM?):
The Windrunner Sisters (
Alleria,
Sylvanas,
Vereesa)
With traps (SV?):
Hemet Nesingwary Casual (
Not Really A Hunter):
Rhonin*
The WowWiki Hunter page lists Brann Bronzebeard as a notable hunter, but I really am not seeing it, and troll Shadowhunters are not exactly hunters (though looking at the page for those it seems that hunter Aspects may have a connection there). Trolls and Dwarfs do seem to be the two races with the strongest tradition of using ranged weapons, the High/Blood elves used to but seem to have rejected that part of their heritage in favor of magic use. In WCIII the basic unit for the Night Elves was the Archer, but I can't remember any named characters that fought in that style--the Night Elves have an affinity for nature in general, but not so much with the way of the hunter except as an offshoot of that.
