Yeah. I know halflings are characterized a bit differently in the 4e handbooks (the only edition I played with any regularity) but the only halfling character I've really seen is Regis from the Drizzt books, and he's pretty exactly a Middle-earth halfling in Faerun.
Hobbits of LotR inspired the Halflings of D&D, so yes they count!
