  Van Wyck-Lefferts Tide Mill (/væn ˈwaɪk/ van WYKE) is a historic tide mill located at Lloyd Harbor in Suffolk County, New York. It was built about 1793 and is a 3+1⁄2-story, gable-roofed, timber-framed rectangular building little altered since the early 19th century. The property also includes the earthen mill dam with sluice gates. The Nature Conservancy, which owns the mill, offers free boat tours to the site from May through October.
  
  It was added to the National Register of Historic Places in 1978.
