It is considered part of the greater Glen Cove area, which is anchored by the City of Glen Cove. The population was 5,062 at the time of the 2020 census.

Sea Cliff incorporated as a village in 1883, with the growing community seeking to gain home rule powers and better control local affairs. The community's public library initially opened in 1894. It formally became a village-administered agency in 1927, through a transfer of charter. In 1968, the village moved its government offices and administrative facilities to its current location in the former Sea Cliff Methodist Church building and parsonage, which had been donated to the village by the church. The library followed suit in 1970, when it, too, moved into the building. The Sea Cliff Museum opened within the building later in the decade, following the United States Bicentennial. In March 2025, Robert Ehrlich, the founder of Pirate's Booty, falsely claimed to be the mayor of Sea Cliff during a "tense standoff at Village Hall", making reference to the Citizen Empowerment Act. Village officials refuted Ehrlich's claim. Ehrlich ran for mayor as a write-in candidate, but lost to incumbent Elena Villafane by a vote of 1,064-62.
