A charabanc or "char-à-banc" (often pronounced "sharra-bang" in colloquial British English) is a type of horse-drawn vehicle or early motor coach, usually open-topped, common in Britain during the early part of the 20th century. It has "benched seats arranged in rows, looking forward, commonly used for large parties, whether as public conveyances or for excursions". It was especially popular for sight-seeing or "works outings" to the country or the seaside, organised by businesses once a year. The name derives from the French char à bancs ("carriage with benches"), the vehicle having originated in France in the early 19th century.

Although the vehicle has not been common on the roads since the 1920s, a few signs survive from the era; a notable example at Wookey Hole in Somerset warns that the road to the neighbouring village of Easton is unsuitable for charabancs. The word is in common usage especially in Northern England in a jocular way referring to works outings by coach.

In Australia a modern similar type of bus or motorcoach, with two lateral doors for each row of seats, survived up to the 1970s and was referred to as side loader bus; but all or most of them were not open-topped. One such a bus based in Echuca, Victoria, has been restored and is used at the Port of Echuca on some public holidays and special events.

Buses with similar arrangement of doors and seats are a common equipment for the antiriot squads of many police forces, as the arrangement lends itself to the squad exiting the vehicle quickly.
