Glen Cove is a city in Nassau County, on the North Shore of Long Island, New York, United States. The city's population was 28,365 at the time of the 2020 census.

Of Nassau County's five municipalities, Glen Cove is one of two that are cities, rather than towns – the other being Long Beach.

Glen Cove was considered part of the affluent, early 20th-century Gold Coast of Long Island, as the properties located along the area's waterfront were initially developed as large country estates by wealthy entrepreneurs and businessmen (such as J.P. Morgan, Phipps, Pratt, and Prybil).[3]

Historically, with the onset of the Industrial Revolution, Glen Cove blossomed in the areas of manufacturing, agriculture and local retail, all of which were operated and staffed by a diverse workforce. The local opportunities—for potential business owners, entrepreneurs, and those seeking employment—attracted numerous immigrants from Europe, largely from Ireland, Italy, and Eastern Europe. Since the 20th century, Glen Cove has also become the home for new waves of immigrants seeking opportunities from Central and South America, as well as parts of Asia.
