The Seattle trolleybus (or trolley[4][5][6]) system forms part of the public transportation network in the city of Seattle, Washington, operated by King County Metro. Originally opened on April 28, 1940, the network consists of 15 routes, with 174 trolleybuses operating on 68 miles (109 km) of two-way parallel overhead lines.[2] As of the second quarter of 2024, the system carries riders on an average of 39,900 trips per weekday,[7] comprising about 18 percent of King County Metro's total daily ridership.
Of the four trolleybus systems currently operating in the U.S., the Seattle system is the second largest (by ridership and fleet size), after the San Francisco system.[8]
