What Companies Are Headquartered on Long Island?

Long Island serves as the corporate home of several large public companies, private businesses, nonprofit organizations, and American subsidiaries of international corporations. Some maintain global headquarters on the island, while others, such as Canon U.S.A., operate their United States or Americas headquarters here.

Among the most prominent examples is Canon U.S.A., which maintains its corporate headquarters at One Canon Park in Melville. Canon U.S.A. is the American subsidiary of Japan-based Canon Inc. and oversees imaging, printing, camera, and business technology operations in the United States.

Melville is also home to Henry Schein, a major distributor of dental and medical products, and MSC Industrial Supply, a distributor of metalworking tools, maintenance products, and industrial equipment.

The community is also home to The Hain Celestial Group, whose portfolio includes food, beverage, and personal-care brands.

Northwell Health, one of the largest healthcare providers in New York, is headquartered in New Hyde Park.

These headquarters are part of a broader business environment that includes manufacturers, healthcare providers, technology firms, financial companies, construction businesses, retailers, hospitality operators, tourism businesses, and professional service providers. Long Island’s proximity to New York City, access to a large regional workforce, and network of highways, rail lines, airports, and commercial centers have helped support this diverse economy.

Corporate offices are particularly concentrated along the Route 110 corridor in western Suffolk County and within the office districts of central and western Nassau County. These areas contain the headquarters of major organizations as well as regional offices, professional firms, research facilities, distribution operations, and privately owned businesses.
