The James William Beekman House (also known as "The Cliffs") is a historic house located on West Shore Road in Oyster Bay, Nassau County, New York.

It was designed by noted English architect Henry G. Harrison in 1863 and built for New York Hospital vice-president James William Beekman (1815-1877).

It is a two-story, rectangular wood-framed dwelling with a steeply sloped, cross-gabled roof designed in the Gothic Revival style.

It features hipped roof dormers, a relatively simple one story verandah, and is situated on a flat plateau atop a rocky outcropping.
