List of trolleybus systems
This is a list of cities where trolleybuses operate, or operated in the past, as part of the public transport system. The original list has been divided to improve user-friendliness and to reduce article size. Separate lists—separate articles in Wikipedia—have been made for the following countries:

Americas
Brazil
Canada
United States
Europe (Note: countries not listed here are included in this article; see Contents table below)
France
Germany
Italy
Russia
Spain
Switzerland
Ukraine
United Kingdom

This page also provides references that are applicable to all parts of the complete list. Bold typeface for a location city indicates an existing trolleybus system, currently in operation (temporary suspensions not counted), or a new system currently under construction. Africa

Note: Tests began 18 September 1949 along tramway lines using "all-service vehicles" (dual-mode buses) purchased secondhand from Newark, New Jersey, US. The tests did not involve building new or converting existing supply because Havana's tramway had twin-wire overhead. Regular service was not operated. Ecuador

Mexico

Note: The Mexico City trolleybus system was long thought to have opened in April 1952, but is now known to have opened more than a year earlier, in March 1951. Previous to that, there was an experimental line, for testing without passengers, in 1947 or 1948. Peru

Notes for the two tunnel trolleybus lines:
 The 6.1 km Kanden Tunnel Trolleybus line operated almost entirely in tunnel, through a mountain, and connected Ōgizawa Station with Kurobe Dam, for tourists and hikers. The transport service continues to operate, but no longer uses trolleybuses. Ōgizawa Station is in Ōmachi city, Nagano Prefecture. The affiliated 3.6 km Tateyama Tunnel Trolleybus line, similarly, operates entirely in tunnel and connects Daikanbo with Murodō. The line is located in Tateyama town, Toyama Prefecture. Both lines are part of the Tateyama Kurobe Alpine Route. This passes through Chūbu-Sangaku National Park (also known in English as "Japan Alps National Park"). Kazakhstan

Note: A Russian-language source  states that system in the city of Turkistan became an unrealised project. Kyrgyzstan

Malaysia

Mongolia

Myanmar

Nepal

North Korea

Note: Due to the incredibly limited streetview in North Korea and limited information, the main sources for trolleybus systems are national articles, tourist-related media, or satellite images. Some previously speculated systems in the central areas of Hyesan, Sunchon, Rajin-guyok (Sonbong county), Songrim, Kusong, and Haeju were largely disproven by available photos and videos, which show no trolleybuses of any kind. Some smaller systems may still be undiscovered. There is some unverified evidence of trolleybuses in the following towns:
Yonsan County images depict something similar to a trolleybus overhead. Philippines
