List of trolleybus systems in the United States

It includes all trolleybus systems, past and present.

In this list, boldface type in the "location" column and blue background colored row indicates one of the four U.S. trolleybus systems still in operation.

Dual-mode (diesel-trolley) buses operated 15 September 1990 – 24 January 2005 on routes using the Downtown Seattle Transit Tunnel.

The overhead wire system in the tunnel was not connected to that used by surface trolleybus services.
