Institute of Arab & Islamic Art

Galleries cluster harder than almost anything else in New York. ZIP 10002 holds 124 of them and 10013 holds 122, with 10001 behind at 103, which means an afternoon on foot covers more of this list than a day of travel would elsewhere.

The directory has 2,667 galleries in total. Websites are nearly as common as phone numbers, 2,215 against 2,377, which fits a business built on showing the work before anyone walks in. Opening hours and current shows live on the gallery's own site; this page does not track either, so follow the link before you go. Listings labeled Sponsored are paid placements and are marked as such. Galleries can claim their entry here and keep the address and website current.
