Mount Sinai was first settled in the 1660s and was known by the name of Old Mans until a name change in the 1840s. Initially an agricultural hamlet, it transitioned into a popular resort town in the late-19th century and developed into a suburb of New York City in the mid-20th century. While primarily a residential community, the hamlet contains Mount Sinai Harbor and its popular public beach, Cedar Beach.
