Glenbrook is a census-designated place (CDP) on the east shore of Lake Tahoe in Douglas County, Nevada, United States. The population was 215 at the 2010 census. Beach and Bay are for residents and renters living in Glenbrook's gated community. There is no public access to the beach or bay.
The community is named after the Glenbrook House hotel and is at an elevation of 6,250 feet (1,900 m). Glenbrook is included in the Gardnerville Ranchos micropolitan statistical area.
As the oldest settlement on Lake Tahoe, Glenbrook played a significant part of Nevada's statehood as the main supplier of timber to the Comstock Lode and Virginia City. The first settlers of the valley, which included Captain Augustus W. Pray, arrived in 1860. Pray built a sawmill in 1861. The community took its name from the former "Glenbrook House hotel", which in turn was named after two primary local geographic features — Glen, a secluded valley, and Brook, a small stream. From forested areas near the lake, logs were driven down stream or barged to Glenbrook mills.
