This is a list of the federal highways in Brazil. The current numbering system has existed since 1964, with changes in 1973.

Brazilian federal road names are composed of the ISO 3166 code "BR", a dash and three numbers. State highways in the country are classified as YY-XXX, where YY is the abbreviation of the state where the highway is located and XXX is a number. The first digit in the number determines which of the five categories the National Road System divides it into.
