This is a list of trolleybus systems in France by région. It includes all trolleybus systems, past and present.
Note for Nancy: TVR opened 28 Jan 2001, replacing dual-mode bus operation. Operation suspended 9 Mar 2001 - 13 Mar 2002 because of technical problems. TVR, Transport sur Voie Réservée, is the Guided Light Transit system, using a centre guide rail and marketed as "Trams sur pneus" (trams on tyres). In Nancy, TVR surface guidance only covers a portion of the route, and the vehicles are able to operate away from the guide rail in electric mode, using trolley poles, and thus the system is trolleybus, despite the Nancy operator's marketing it as the tram. TVR systems elsewhere use pantographs, and consequently are not commonly regarded as trolleybus systems (see note at bottom of list).
Note: The TVR, or GLT, system in Caen and the Translohr system in Clermont-Ferrand are not listed, as they not commonly considered to be trolleybus systems, since their vehicles use pantographs to collect current and therefore are not able to operate away from the surface guideway while remaining in electric mode. The GLT vehicles in Nancy, by comparison, are able to do so, as they use trolley poles to collect current, so the Nancy system is considered to be a trolleybus system.
