South Nyack is a hamlet and census-designated place in the town of Orangetown in Rockland County, New York, United States.

It is located north of Grand View-on-Hudson, northeast of Orangeburg, east of Blauvelt State Park, south of Nyack and west of the Hudson River.

[3] Following the extension of the Northern Branch of The New Jersey Railroad into the area in the mid-19th century, rapid growth ensued.

Town government no longer being seen as an effective means of dealing with the area's needs, village incorporation was discussed.

[4] On December 17, 2020 residents voted 508-292 to dissolve the village in favor of becoming an unincorporated area within the town of Orangetown.

[5][6] The dissolution vote did not take immediate effect, and the village continued to exist until March 31, 2022, after which it became a hamlet within the Town of Orangetown.

The company still holds in its possession its first apparatus, which dates back to 1749 and survived a fire in the firehouse some years ago.

The Hamlet of South Nyack is the western terminus of the Tappan Zee Bridge, which connects the village to Tarrytown in Westchester County.

South Nyack was formerly served by the Northern Branch of the Erie Railroad, with service to Pavonia Terminal in Jersey City.

[13] South Nyack is also served by Rockland Coaches/Red and Tan Lines Buses (operated by Coach USA) to the Port Authority Bus Terminal and George Washington Bridge Bus Terminal in New York City.
