The Boston-area trolleybus system formed part of the public transportation network serving Greater Boston in the U.S. state of Massachusetts. It opened on April 11, 1936, with a large network operating for the next quarter-century. Measured by fleet size, the Boston-area system was the second-largest trolleybus system in the United States at its peak, with only the Chicago system having more trolleybuses than Boston's 463. After 1963, the only remaining portion was a four-route cluster operating from the Harvard bus tunnel at Harvard station, running through Cambridge, Belmont, and Watertown. The Massachusetts Bay Transportation Authority took over the routes in 1964.
A Warsaw trolleybus system formed part of the public transport network of Warsaw, the capital city of Poland, during two separate periods. The first trolleybus system was established in 1946 and lasted until 1973. It had a maximum of 10 routes. The second system, comprising only one route, was in operation from 1983 until 1995. Between 1992 and its closure, it was operated by Zarząd Transportu Miejskiego (ZTM), in English the Public Transport Authority (Warsaw).
Electric Transit, Inc. (ETI) was a joint venture between the Škoda group in the Czech Republic and AAI Corporation in the United States which made trolleybuses for the Dayton and San Francisco trolleybus systems, constructing a total of 330 trolleybuses. ETI was formed in 1994, and ownership was divided as 65% by Škoda and 35% by AAI. The latter was a wholly owned subsidiary of United Industrial Corporation. Up to that time, Škoda had built more than 12,000 trolleybuses since 1935, but none for cities outside Europe and Asia. The ETI joint venture was dissolved in 2004, shortly after an unsuccessful bid to supply trolleybuses to Vancouver.

The Coimbra trolleybus system formed part of the public transport network in the city of Coimbra, Portugal. Opened in 1947, it supplemented, and then eventually replaced, the Coimbra tramway network. Service was suspended in March 2021 because of road construction, and officials stated that the suspension was temporary, but in late 2022 the mayor indicated that any resumption of trolleybus service would not occur until after completion of construction of a new Bus Rapid Transit line, around late 2024. However, in July 2024, the city council voted not to resume service – to make the suspension a permanent closure – albeit with a proposal floated for a future tourist trolleybus operation along the banks of the Mondego River, without further detail given.

The Avellino trolleybus system forms part of the public transport network of the city of Avellino and the province of Avellino, in the region of Campania. Trolleybuses originally served the city from 1947 to 1973, on a route that also extended outside the city to the neighbouring towns of Atripalda and Mercogliano, and then the system closed. However, in the 2000s work to build a new trolleybus system got under way and new vehicles were purchased for it in 2007, and were delivered in 2014. The project experienced several delays after the start of construction in 2009, but most issues had been resolved by 2020 and construction was largely completed by 2021. Throughout its planning and construction, it was inaccurately referred to as the "metropolitana leggera", when in fact it was never planned to be a rail line, and always planned to be a trolleybus line. The last round of testing took place in December 2022 and January 2023, and the new trolleybus system opened for service on 3 April 2023.
