An International Driving Permit (IDP), often referred to as an international driving license, is a translation of a domestic driving licence that allows the holder to drive a private motor vehicle in any country or jurisdiction that recognises the document. The term International Driving Permit was first mentioned in the document prescribed in the International Convention relative to Motor Traffic that was signed at Paris in 1926, and is a translation of the French 'permis de conduire international', or 'international driving licence'. The Paris treaty, and all subsequent, use the word 'permit' exclusively in relation to all kinds of driving licence.

International Driving Permits are governed by three international conventions: the 1926 Paris International Convention relative to Motor Traffic, the 1949 Geneva Convention on Road Traffic, and the 1968 Vienna Convention on Road Traffic. When a state is contracted to more than one convention, the newest one terminates and replaces previous ones.

The IDP, whose A6 size (148 × 105 mm) is slightly larger than a passport, has a grey cover and white inside pages. The outside and inside of the front cover shall be printed in (at least one of) the national language(s) of the issuing State. The last two inside pages shall be printed in French, and pages preceding those two pages shall repeat the first of them in several languages, which must include English, Russian and Spanish.

IDPs are issued by a national government directly, or through a network of AIT/FIA organizations, authorized by their governments to issue them. For the latter case those issuing organizations are mostly automobile associations, such as American Automobile Association in the United States, Norwegian Automobile Federation in Norway and Riksförbundet M Sverige in Sweden. As there are many unofficial sellers on the internet, the AIT/FIA has created an approved directory to all IDP issuing organizations in the world.

To be valid, the IDP must be accompanied by a valid driving licence issued in the applicant's country of residence. An IDP is not required if the driver's domestic licence meets the requirements of the 1949 or 1968 convention; the domestic licence can be used directly in a foreign jurisdiction that is a party to that convention. In addition, other arrangements eliminates the need of an IDP in some countries, such as the European driving licence valid within the European Economic Area.
