Grands Boulevards (French pronunciation: [ɡʁɑ̃ bulvaʁ]), formerly named Rue Montmartre (1931–1998), is a station on Lines 8 and 9 of the Paris Métro.

[1] The section of both lines from just east of Richelieu–Drouot to west of République was built under the Grand Boulevards, partly on the border between the 2nd and 9th arrondissements, that replaced the Louis XIII wall and is in soft ground, which was once the course of the Seine.

This caused confusion for non-Parisians and tourists, as the Montmartre neighbhorhood lies significantly north of the station.

In 1966, an attempt was made to improve clarity by covering the original nameplates with signs reading "Rue Montmartre," but confusion continued.

Two in number per stopping point, they are isolated in two half-stations separated by a central wall due to their construction in unstable land.
