State Route 605 was a north–south state highway in the Las Vegas urban area. SR 605 comprised a portion of Paradise Road.

SR 605 began at Tropicana Avenue (SR 593). From there, it followed Paradise Road north to its terminus at Sahara Avenue (SR 589). The portion of Paradise Road from Harmon Avenue (near the Hard Rock Hotel and Casino) south to Tropicana Avenue was a multi-lane one-way street southbound.

State Route 605 was relinquished to local control in 2001.

Paradise Road is considered the main entrance to McCarran International Airport. The northern leg of the Las Vegas Monorail runs down the center of the road for a portion of the route and then along the eastern side to the monorail's northern terminus.
