A jaunting car is a light two-wheeled carriage for a single horse, with a seat in front for the driver. In its most common form with seats for two or four persons placed back to back, with the foot-boards projecting over the wheels and the typical conveyance for persons in Ireland at one time (outside jaunting car). Also with passenger seats facing each other (inside jaunting car)

There were two main varieties of jaunting car: the "outside jaunting car", or "outside car", the more common type, in which the passengers faced outward over the wheels, and the "inside jaunting car", or "inside car", considered to be more "genteel", in which the passengers sat with their backs to the sides of the car and faced each other. Anthony Trollope described the "inside jaunting-car" as "perhaps the most uncomfortable kind of vehicle yet invented."

A third variety, the "covered car", was an inside car with oiled canvas arranged on all sides to protect the passengers from the weather, at the expense of visibility.

The first part of the term is generally taken to be identical with the verb to jaunt, now only used in the sense of to go on a short pleasure excursion, but in its earliest uses meaning to make a horse caracole or prance, hence to jolt or bump up and down. It would apparently be a variant of "jaunce", of the same meaning, which is supposed to be taken from old French jancer.
