Annadale is a middle-class neighborhood on the South Shore of the borough of Staten Island in New York City.

The site was purchased and buildings demolished at the end of the 20th century so that several large, upscale homes could be constructed.

Annadale once had abundant woodland, but much of it was cleared in the last three decades of the 20th Century to make room for new homes.

However, a city park in the heart of the neighborhood was converted into a wildlife preserve; known as Blue Heron Park Preserve, it covers 222 acres (898,000 m2), much of it consisting of ponds, swamps and small streams which empty into nearby Raritan Bay.

The northwestern part of Annadale is now often regarded as a separate neighborhood known as Arden Heights.
