Casa de Shenandoah, Private estate in Paradise, Nevada, United States.

Casa de Shenandoah is a large private estate near Las Vegas designed as a sprawling compound with multiple residential buildings and recreational facilities. The property features dedicated spaces for collecting vehicles, housing animals, and conducting specialized agricultural operations.

Wayne Newton bought five vacant acres here in 1966 and added land until the ranch reached 39.5 acres. By 1973 it held three houses and a horse hospital, and a $4 million southern-style mansion designed by Newton was completed in 1978. The estate opened as a public attraction on September 18, 2015, closed in April 2018 and was sold in 2019 to Smoketree LLC.

The estate served as a venue for performances, political gatherings, and social events, hosting notable figures including President Ronald Reagan in 1982.

The estate closed to the public on April 24, 2018, and the attraction permits were withdrawn that July, so the grounds and mansion are not open for tours. The 39.5-acre site lies in Paradise, Nevada, near Sunset Park, and is bounded by straight roads on two sides. Viewing is limited to what can be seen from the surrounding streets.

Newton kept deer, ducks, swans, wallabies and peacocks that gathered at the estate's lakes, and neighbours sometimes threw animals such as rabbits over the wall, believing the ranch was a sanctuary. A 1929 Duesenberg once owned by Howard Hughes, Newton's former boss, was among the cars in the on-site garages.
