Porte de Clignancourt (French pronunciation: [pɔʁt də kliɲɑ̃kuʁ]) is a station of the Paris Métro, the northern terminus of line 4, situated in the 18th Arrondissement.

Beyond the turning loop lie a series of storage sidings and the main depot for Line 4 in Saint-Ouen.

The term "porte" refers to a gate of the Thiers Wall built to defend Paris between 1841 and 1844 and demolished in the 1920s.

The white ceramic tiles are flat and cover the walls, the roof, the tympans and the outlets of the corridors.

The advertising frames are green and cylindrical and the name of the station is written in capital letters on enamelled plates.
