artHARLEM, Inc. is a volunteer-run, minority-led 501(c)(3) nonprofit based in Harlem, Manhattan, dedicated to sustaining the neighborhood's artistic community. Its flagship program is the Harlem Open Artist Studio Tour (HOAST), an annual event in which visual artists with studios in Harlem open their spaces to the public and sell work directly to visitors. Artists join by maintaining a Harlem studio, an individual website, and a membership fee. The organization supports the tour with a mobile navigation app, printed maps, and a press room for media, and it relies on artist applications, donations, and volunteers to operate.
