The Greenbrier is a palatial luxury resort located in the Allegheny Mountains near White Sulphur Springs in Greenbrier County, West Virginia, in the United States.

Since 1778, visitors have traveled to this part of the state to "take the waters" of the area. Today, The Greenbrier is situated on 11,000 acres (17 sq mi; 45 km2) of land with 710 guest rooms, 20 restaurants and lounges, more than 55 indoor and outdoor activities and sports, and 36 retail shops. 1800 "ladies and gentlemen" offer authentic southern hospitality to guests.

The current Greenbrier was built in 1913 by the Chesapeake & Ohio Railway and was owned for much of its history by that company and its successors, including the CSX Corporation. Following years of heavy losses, CSX placed the hotel into bankruptcy in 2009. Justice Family Group, LLC, a company owned by local entrepreneur Jim Justice, subsequently bought the property and guaranteed all debts, resulting in dismissal of the bankruptcy. Justice promised to return the hotel to its former status as a five-star resort and to introduce "tasteful" gambling for guests as a revenue enhancer. The Greenbrier Hotel Corp. today operates as a subsidiary of Justice's company.
