Stateline is a census-designated place (CDP) on the southeastern shore of Lake Tahoe in Douglas County, Nevada, United States. It lies next to the California state line and City of South Lake Tahoe. The population was 842 at the 2010 census. The population swells considerably during the busy winter and summer seasons, due to the high number of hotel rooms and rental accommodations available.
Stateline is home to five open casinos, four of which qualify as resorts: MontBleu (formerly Caesar's), Harrah's Lake Tahoe, Hard Rock Hotel & Casino Lake Tahoe (formerly Horizon), and Harveys Lake Tahoe. Until its closure on April 14, 2020, the Lakeside Inn catered to locals and modest gamblers.
Many of the hotels in the neighboring city of South Lake Tahoe, California, organize buses to take residents to the casinos in Stateline. Stateline and South Lake Tahoe are effectively a single settlement, with the state line intersecting with U.S. Route 50 immediately after the Harrah's and Harvey's casinos. As commercial gambling establishments are illegal in California unless built on Indian reservations, the casinos are extremely popular with California residents due to their strategic location right on the state line.
Another well-known feature of Stateline is Kingsbury Grade, which runs up and over a mountain pass, rising from Lake Tahoe and dropping down to the Carson Valley on the other side.
