Quigley's Castle is a historic house museum and garden at 274 Quigley Castle Road, Arkansas, and is one of the most unusual houses in northwestern Arkansas. The house was designed by Elise Quigley and built in 1943 by Albert Quigley.

The exterior of the house is decorated with the collection of rocks Elise Quigley had accumulated since childhood. The house was specifically deisgned by Quigley to accommodate a two-story space for tropical plants. Over the years Elise Quigley's gardens expanded to take over much of the property.

In 1950 the family began charging admission to tour the home, a practice that continues today.
