Roads in Portugal are defined by the Plano Rodoviário Nacional (PRN, English: National Road Plan), which describes the existing and planned network of Portuguese roads. The present plan in force is the 2000 National Road Plan (PRN 2000), approved in 1998. It replaced PRN 1985, which itself had replaced PRN 1945.

The Portuguese road infrastructure was considered the best in Europe and the second best in the world by the World Economic Forum in its Global Competitiveness Report for 2014–2015.^[1] In the 2017–2018 report, it was considered to 8th best in the world.^[2] Nevertheless, all of these data were obtained through nothing more than an opinion survey of selected business executives.^[3]

The scenic road between Peso da Régua and Pinhão, in Trás-os-Montes region, was considered the world's best driving road, according to the Avis Driving Index.^[4] This road is a section of the N 222 which follows the Douro Valley.
