Reverie Cove is a historic summer estate on Harbor Lane in Bar Harbor, Maine. It was designed by local architect Fred L. Savage and built in 1895, and is a particularly opulent example of Colonial Revival architecture. A later owner of the property was New York City mayor Abram Hewitt. The house was listed on the National Register of Historic Places in 1982, and as part of the Harbor Lane-Eden Street Historic District in 2009.
