Boulevard Périphérique is the French term for a ring road (US: beltway), a motorway encircling or orbiting a large city.

The most famous of these is the Périphérique around Paris, a frequently congested stretch of motorway, which, unusually, does not feature a hard shoulder, and gives priority to entering vehicles. It is the generally-accepted boundary of the city. France's anglophone community occasionally refers to the Parisian example as the "Périfreak", attesting to the many accidents and thick traffic associated with it.
