Gyrodyne Company of America, Inc. is a real estate investment trust that owns, leases, and manages commercial properties along the Eastern Coast of the United States.
For the next 24 years the company was engaged in the design, testing, development, and production of coaxial helicopters, primarily the Gyrodyne QH-50 DASH drone for the U.S. Navy.
In 1975, Gyrodyne began converting its helicopter manufacturing facilities into rental space suitable for light industry.

Today Gyrodyne owns, manages, and leases four properties: two in eastern Long Island, one in southern New York, and one in Northern Virginia.
