McCarran International Airport is the primary commercial airport serving the Las Vegas Valley, a major metropolitan area in the U.S. state of Nevada. It is in Paradise, about 8.0 km south of Downtown Las Vegas. It is named after the late U.S. Senator Pat McCarran, a member of the Democratic Party who contributed to the development of aviation both in Las Vegas and on a national scale.

The airport was built in 1942 and opened to commercial flights in 1948. It has undergone significant expansion since then and has employed various innovative technologies, such as common-use facilities.
