Winchester is an unincorporated town[2] and census-designated place (CDP) in Clark County, Nevada, United States that contains part of the Las Vegas Strip.

[6] In 1950, mayor Ernie Cragin of Las Vegas sought to annex the Las Vegas Strip, which was unincorporated territory, in order to expand the city's tax base to fund his ambitious building agenda and pay down the city's rising debt.

[7] A group of casino executives, led by Gus Greenbaum of the Flamingo, lobbied the county commissioners for town status, which would prevent the city from annexing the land without the commission's approval.

[12] Town "A" of Paradise included the areas that lay within a Las Vegas school district, extending from the city limits to a point one mile south, while Town "B" included the areas within the Paradise school district.

To the north it borders Las Vegas, to the west and south is the CDP of Paradise, and to the east is Sunrise Manor.

Relative to streets, it is the area bordered by Sahara Avenue on the north, Boulder Highway on the east, Desert Inn Road on the south and the Union Pacific Railroad tracks on the west, with a few additional enclaves west of Interstate 15.

According to the United States Census Bureau, the CDP has a total area of 4.3 square miles (11 km2), all land.
