The international E-road network is a numbering system for roads in Europe developed by the United Nations Economic Commission for Europe (UNECE). The network is numbered from E1 up and its roads cross national borders. It also reaches Central Asian countries like Kyrgyzstan, since they are members of the UNECE.

Main international traffic arteries in Europe are defined by ECE/TRANS/SC.1/2016/3/Rev.1 which consider three types of roads: motorways, limited access roads, and ordinary roads.

In most countries, the roads carry the European route designation alongside national designations. Belgium, Norway and Sweden have roads which only have the European route designations (examples: E18 and E6). The United Kingdom, Albania and the Asian part of Russia only use national road designations and do not show the European designations at all. All route numbers in Andorra are unsigned. Denmark only uses the European designations on signage, but also has formal names for every motorway (or part of such), by which the motorways are referred to, for instance in news and weather forecasts. In Asia, Turkey and Russia show the European designations on signage; this is not the case in many other Asian countries.

Other continents have similar international road networks, e.g., the Pan-American Highway in the Americas, the Trans-African Highway network, and the Asian Highway Network.
