Jericho is an unincorporated community (or "hamlet" in local parlance) and Census Designated Place located on Long Island in New York State within Nassau County in the Town of North Hempstead. The majority of the hamlet is part of the Jericho Union Free School District, which it shares with parts of neighboring Old Westbury, Brookville, and Muttontown, while a small portion of the hamlet's eastern end is part of the Syosset Central School District, which it shares with neighboring Syosset. Commuter rail access to New York City is available from Hicksville station in neighboring Hicksville.

Jericho is a serene yet vibrant hamlet set amidst a bucolic landscape. Verdant facilities that offer high-end recreational pursuits such as horseback riding and polo grace the surrounding region with a regal air. And destinations like a more than 100-year old cider mill provide rural charm. But the biggest draw has long been the highly-prized public schools, which remain the center of community life. In addition to the stellar schools, residents love the highly-regarded public library, as well as the numerous international dining and grocery establishments.
